Bedtime Basics

How I Do The Bedtime Routine Solo (with Preschooler, Toddler, & Baby)

Bedtime routines can be overwhelming. Especially if you’re doing them alone… and with multiple children. Here’s how I manage with three:

UPDATE: I wrote this 2 children (and years) ago, but thought it would be helpful to show how a mom can create a routine for bedtime with little ones, even when she does it all.

My husband works 3 or 4 nights a week.

So… on those nights, bedtime routine is all me.

Within roughly a 30 minute period I put all three kids (3 years, 2 year, 1 year) in their beds for some zzz’s.

Some nights I think I will rip my hair out or just make myself faint and pray I wake up to children who’ve fallen asleep in their own beds after an angel brushed their teeth.

Alas… but 90% of the time I have the routine down pat and all get tucked in with very minimal fuss.

Avoid Second Winds At Bedtime

This free guide gives you the main 4 reasons little ones won’t settle at bedtime (or stall, keep coming out, cause power struggles, etc.) and what to do!

Here’s how I do the bedtime routine for my preschooler, toddler, and baby alone

6:30 pm – 6:45 pm

While reading individually to children is very important, it’s just not something I’ve found success with at bedtime when I’m on my own. I generally read to all the kids at once on the couch from 6:30 pm onwards.

  • I  try to keep them seated on the couch or the floor in front of me and direct them back if they begin to get rambunctious. This settles them.
  • I rotate books between the various levels, board books to easy reads to Fancy Nancy.

The goal is to get everyone into bed between 7-7:30pm most nights. I begin the process a few minutes before 7 and everyone is generally tucked in tight by 7:30pm.

I’ve found that altering this time by even 20 minutes can result in contagious meltdowns. And let me tell you, that’s something I try actively to avoid when I’m on duty alone.

6:45 pm – 7:00 pm

I’ve found it’s easier to put my youngest to bed first because the older kids are able to sit relatively still during this part.

Certainly if I use calm down tricks.

  • I give my littlest a little snack around this time and some milk.
  • Then, I change diaper, put on pajamas, and kiss and cuddle until I’ve had my fill, or he’s had his.
  • I pray over him and then go to handle the older kids.
  • While I’m putting my littlest to bed I have my older two kids either go to their rooms (you may have to walk them there) or wait quietly reading in the main living area.

Goodnight Bedtime Battles

This workshop will give you a simple, sanity-saving bedtime system that actually works—one that helps your kids wind down, fall asleep without endless stalling, and stay asleep (so you can finally get some rest).
Start Now

7:00 pm – 7:30 pm

When I’ve got the littlest to bed, I move on to the other kids.

Then…

  • I get everyone dressed in pajamas, teeth brushed, and ready to go to their respective beds.
  • Send my eldest to her room to quietly read a book or play with her dolls while I put her brother to bed. I turn on the fan, monitor, and hug and kiss and cuddle until he wriggles out of my arms. I pray and sing to him and off to bed he goes.
  • Then I go to my daughter’s room who, at 3, is the most challenging to get to bed without a million questions. Not only do we pray and sing songs, she wants stories that I start and she can finish.

She likes her clothes, blankets, and nightlight just so.

She wants to drink water. So, I usually give her one gulp before laying down. I tell her I’ll check on her later and daddy will too when he gets home.

Organized & On Task

I try to be organized, compartmentalized, and about the business of bedtime.

After dinner (before bedtime lead up) we can play and be a bit rambunctious. Then, when it’s nearing bedtime, I get them to remain in one place or do something quiet as much as I can.

I remind them frequently that “it’s almost time for bed” so they come willingly when it’s time.

After dinner I get on to the dishes (that I didn’t wash while cooking) immediately. That way the task isn’t looming over me as I finally get the kids down. Just before bedtime wind down- I get the kids to help tidy up.

Since all toys go in baskets that they are familiar with, this process doesn’t generally take too long once they’re motivated. I direct one to put up books, another to put away toys in this area, etc.

Then, I direct them to return certain items to their place.

It is a tremendous weight off my shoulders to know that – after they’re tucked in bed – I honestly don’t have any household related chores to do.

Sanity Saving Tips:

Here are a few tried and true tips that really have helped me steer away from the crazy:

  • Give them a calm directed activity (or do it with them) for the 30 minutes leading up to bed
  • Get them to help you tidy up and clean where possible so your recharge time will be maximized.
  • Corral the little ones and direct them to stay in one area. This way they don’t go tearing up the house while you’re putting one kid down.
  • A small snack goes a long way towards helping them sit still and get calm.
  • Use white noise so that the sounds of those still awake doesn’t prevent those already in bed from settling.

So… that’s about it really. Whole house clean, all kids in bed, mommy relaxes. Or, more accurately, goes to bed by 9pm. 🙂

Is Witching Hour The Same As Colic?

Is witching hour the same as colic or are they different? let’s figure out which one it is so you what to do.

Here comes the evening hours and you are gearing up for some tears. Baby is fussy, inconsolable, not wanting to sleep, and you’ll try ANYTHING to try and get baby some relief.

The question is… if you want to put a name on it.

Is it witching hours or colic?

Can you tell a difference?

The answer is: yes.

As a certified baby and toddler sleep consultant and mom of 5 I can tell you that there’s a difference. Having had 5 babies, none of which had colic, but all of which had witching hours from time to time, you can know.

baby crying during witching hour with colic

How to know if baby crying every night is colic or witching hours

Colic is diagnosed by doctors if baby cries for something like 3 hours at a time, at least 3 nights a week, for 3 weeks or more.

There is little to do to comfort a baby with colic except wait for time to pass. One day, around 3 to 4 months you’ll wake up one day and baby will simply not be fussy. Not be crying. They’ll go to bed, sleep, be comforted, and you’ll feel like it was all a bad dream.

Moms survive this period by having help, getting ear plugs if needed, switching out who tries to soothe baby while crying, and a lot of prayer.

How to know if it’s witching hours

Witching hours can last a couple of hours, but they are more random. It may be a night or two a week, but you can usually soothe baby and comfort her.

A good daily routine, an age appropriate bedtime, and wind down routines can go a long way to preventing witching hours. Settle baby in their own crib, give full feeds, and avoid over stimulation. These strategies help witching hours be less frequent and can even eliminate them.

If you move bedtime up, have a good wind down routine, create an optimal sleep environment, help baby settle to sleep and are sure baby is well rested, baby will typically be content.

If you do all these things and nothing works… it’s likely colic.

Sometimes overtiredness manifests as witching hours or even colic

A great starting point if you have a baby who is having witching hours (or you’re trying to rule out colic) in the evening time is to get on a good predictable daily routine. You don’t have to be a slave to the clock or anything, okay.

Don’t send me hate mail.

But, making sure baby’s needs are met in a predictable way means that your baby won’t really need to cry much throughout the day, nor at night. Babies who won’t nap and are super worn out often fuss in the evening hours.

Sleep begets sleep.

Focusing on good naps during the day, good full feeds, and avoiding over stimulation in the evening hours can often eliminate all evening crying.

You still may have some tears, but not nearly as many.

Do Toddlers Have A Witching Hour?

If your toddler is acting like they’re having a witching hour, it’s time to rework their daily schedule for more peace.

Maybe you’ve got a toddler who seems to be melting down, throwing fits, avoiding bedtimes, getting second winds, and being unreasonable. In the sense they aren’t making sense.

You know what I mean.

Perhaps they’re just having a large time of melodrama at a particular interval. You probably wonder if your toddler is having witching hours.

toddler lying on floor having a witching hour

So is my toddler having witching hours or is it just a meltdown?

This is the right question. As a certified baby and toddler sleep consultant I can tell you something. Witching hours are real but they’re usually something little babies have.

Now, toddlers can have their own form of this but it’s usually as a result of overtiredness. Or staying up too late past bedtime. And getting a second wind which makes them appear hyper and not tired at all.

Which is just not true. They just need to be put to bed before they hit that high.

Avoid Second Winds At Bedtime

This free guide gives you the main 4 reasons little ones won’t settle at bedtime (or stall, keep coming out, cause power struggles, etc.) and what to do!

Do witching hours (or regular meltdowns) go away on their own?

Most babies will grow out of witching hours when they are established in good daily naps, good bedtime routines, and are not overtired at bedtimes. Most babies past 4 months old don’t have witching hours unless they have unpredictable days and are overtired.

Toddlers, on the other hand, can meltdown for a variety of reasons. And if they’re having regular meltdowns at the same time every day, THAT’S GOOD NEWS. It means the issue will be easy to isolate.

Is toddler melting down around bedtime?

If your toddler is regularly melting down at bedtime, I’d move bedtime up 30 minutes. Start the bedtime routine earlier, is possible, and then have your little one into the bed 30 minutes before they previously were. This will help beat them to the overtiredness.

This will also prevent them from getting a second wind which causes a whole host of other issues. And causes them to be much more resistant to go to bed, you get into power struggles, and bedtime becomes a battle instead of a lovely peaceful thing.

Is your toddler waking up and having “witching hours” in the night?

As said before, witching hours don’t really happen to toddlers and certainly not in the middle of the night. However, if your toddler IS waking in the middle of the night, or after a few hours of sleep and wanting to come out of their beds, etc. then it’s time to do some sleep intervention.

By sleep intervention I mean a formal type of sleep training that helps teach them to stay in their beds. When done correctly they feel safe, happy, and don’t wake up and call for you. They simply sleep through.

Sometimes around this age toddlers will get some separation anxiety, but the solution isn’t to intervene heavily at night. It’s too create security and safety during the day, and keep boundaries for the night.

Why Is My Baby Crying At Night All Of A Sudden?

If your baby has started crying at night all of a sudden, there could be a few reasons, let’s figure them out one by one.

If your baby has started crying at night all of a sudden, there could be a few things happening. The things like sickness, ear ache, teething, etc. need to be ruled out because those are typically one off things that can be resolved within a day or two.

But if you’ve got a precious baby crying at night all of a sudden and it’s not that, well, we need to dig a little deeper.

Is baby crying at night all of a sudden during the witching hours?

If your baby is a few weeks old and suddenly starts crying in those later afternoon and early evening hours (or sometimes the 7pm to 9pm hours) then it could likely be witching hours.

Here is how to get through the witching hours – if you determine that’s the issue – but sometimes it’s not that. Sometimes baby is a bit older, has been going through everything fine, and then ALL OF A SUDDEN the sleep ain’t happening.

Read: The Top 10 Indicators It’s Time to Sleep Train

Is baby crying all of a sudden out of hunger?

There comes a time – typically around 5 to 7 months of age – when baby is simply more hungry. Infant nutrition needs morph as they grow and by 6 months most babies are absolutely ready to be eating solids. Not 1 or 2 tablespoons a day, but at 3 meals a day.

Including protein, which incidentally, helps baby sleep.

So if baby is crying all of a sudden at night or throughout the night, having night wakings when they haven’t in a long time, I’d rule out hunger. Offer more feeds during the day and add in solids and work to help baby eat a good amount.

If you’re still feeding at night, give baby full feeds. Don’t let babe snack for 5 minutes then back to sleep because you’ll do that on and off all night if what they really need is a good amount of milk.

Is baby crying at night all of a sudden due to a change in routine or circumstances?

Often babies will become overstimulated and need an earlier bedtime. If baby has dropped a nap and then is crying at normal bedtime, may be time to move that bedtime up a bit.

Has someone started caring for baby other than you? Maybe they do things differently during the day and baby is more worn out.

Perhaps baby needs more exercise. Sometimes we think babies don’t need to move and play, but they do! Tummy time, back time on a blanket, or play gyms. Or even just cuddling and playing with other siblings will help baby use up some of their energy.

Why Does My Baby Cry At The Same Time Every Day?

Babies often cry at the same time every day because they’re tired, they’re hungry, or they’re having witching hours. Read on to see more.

If your baby is crying at the same time every day, this is a much easier problem to have than a baby who is fussy all day every day.

As a mom of 5 and certified baby and toddler sleep consultant, trust me.

Depending on the time, there are a few likely reasons why your baby cries at the same time every day.

If your baby cries at the same time every day in the late afternoon / evening period then…

When 5 or 6 pm comes around (sometimes 7 or 8pm depending on the baby) and your baby starts crying, you can typically think it’s a few main things.

First, it could be their witching hours. Witching hours are a super fussy time in that evening hour. They’re typically hard to console but can be minimized and prevented with a good routine, avoiding overtiredness, and getting baby to bed at a good hour.

Read here on how to end baby’s witching hour in 4 steps.

If your baby cries at the same time every morning or during the day then…

If you have a routine down pat for your baby then it’s easy to decipher what cries mean. If baby cries at a certain time, is fed, then perks up, you know it’s hunger. They’re crying as a signal they want to eat.

On the other hand, some babies will cry when they’re tired and then crying at a certain time means they need a nap.

So a good consistent daily routine that helps all of their needs be met in a timely manner will always help you decipher why baby is crying. Crying at very random times unexpectedly clues you in something else is happening as well.

Read: Is Sleep Training a Baby Bad or Dangerous? Let’s Talk Facts!

If baby cries at the same time every night then…

Often babies who aren’t able to transition through sleep cycles on their own have to cry to get mom to come to their aid. They want mom to do whatever it is mom did to GET them to sleep so they can go BACK to sleep.

For some babies, there’s a feed to sleep association. Meaning mom has to feed baby to get them to calm down and get to sleep. If that’s the case, they may wake up at the same time every night as a habit, to feed, to then calm down and go back to sleep.

Baby Bedtime: 4 Essential Elements To Success

Want a baby bedtime that’ll help babe sleep easily and stay asleep? Put these 4 habits into practice and you’ll see baby start snoozing away.

I remember the first time my son started screaming his head off in those evening hours…

I was shocked. 

Whoever started the “sleeping like a baby” phrase had not encountered my firstborn boy at bedtime. Oh no, they hadn’t.

It was in those first few weeks when I realized that this bout of crying in the early evening actually had a name.

These were called the “witching hours.” 

After a few evenings of this I began to feel crazy, panicked, and anxious as evenings approached.

It was hard to handle hours of unhappiness. 

With a lot of reading, experimenting, and asking around… I figured out how to minimize these witching hours. Then, with the next 3 babies, I was able to eliminate those times almost entirely.

Occasionally, if baby was extremely overtired, we’d have a tough time, but otherwise… smooth sailing.

So what’s the key to having a calm and restful bedtime period and longer periods of sleep for little ones?

An effective baby bedtime routine.

4 Essential Elements To A Successful Baby Bedtime Routine

Consider these factors when establishing a baby bedtime routine and you’ll be well on your way to peaceful evenings.

Read: How To Get A Newborn To Sleep Well From Day One

Choose The Time Wisely

While there is no hard and fast rule, most experts agree that an earlier bedtime is better than a later one. When newborns are so little they’re napping on and off all day and night, it isn’t as important.

But once babies reaches 3 or 4 months, establishing a set time, say 8 p.m. or so, means that baby’s body clock will align with bedtime, making things easier.

Use these baby logs and checklists to determine why baby isn’t sleeping well, if that’s an issue.

Read: Cocooning a Newborn & 7 Reasons Why it Can Be Good For The Family

Factors To Consider:

  • Choose a morning wake time, then backtrack to get a bedtime. If you don’t want baby to sleep until 10:00 a.m., don’t put bedtime at 10:00 p.m.
  • Choose a baby bedtime that fits around the other kids’ bedtimes. If it takes you a bit longer with baby than everyone else, put other kids to bed then do baby just after.
  • “They” say that every hour of sleep before midnight counts as two so, unless baby takes a nap that goes on into early evening, don’t push bedtime back too far.

Cluster Feed When Possible

Cluster feeding is when you feed baby closer together than normal in a given period of time.

If you normally feed baby every 3 hours, a cluster feed might be feeding baby every 2 hours from 4:00 p.m. until 8:00 p.m. If you are nursing, cluster feeds are very effective for settled babies.

Benefits of Cluster Feeding

  • The quality of breast milk can deteriorate as the day goes on due to a variety of factors (diet, stress hormones, etc.) so cluster feeds at the end of the day mean baby does not get fussy from hunger due to lower calorie milk. (Here’s how to tell if baby is getting enough milk)
  • Cluster feeds will fill baby’s belly so they’re more likely to go to sleep easier, without fuss, and stay asleep longer.
  • Cluster feeds will help you make sure baby is getting enough of their nutritional needs during the day so they wake less frequently at night.
  • Frequent feeds will keep up your milk supply.
  • Cluster feeding minimizes witching hours. They are somewhat unexplainable and unavoidable, but you can minimize both witching hours and colic by providing baby frequent feeds in a short period of time in the early evening period.

Imagine this…

Imagine going to sleep in your comfy safe bed and then, an hour or two later…  waking up on a new pillow in a new place. Would you be disoriented?

Yes, and you’d probably fully wake up to investigate your surroundings.

  • You can have a separate napping bed than nighttime bed, but be consistent with where you put baby to sleep and where you want them to remain sleep.
  • Choose an area for nap away from the hustle and bustle main living areas of the home. Here’s how to keep noisy siblings from being a problem.
  • Have a naptime routine that will help baby calm down from the normal stimulation of the household to being ready to sleep.

A Good Wind Down Routine

A good wind down routine is an essential ingredient to helping baby’s body calm down in order to sleep.

If baby is in a room with loud siblings then you march him into his nursery, turn off the lights, and put him in his bed, that’s a recipe for frustration and crying.

In order for baby’s body to begin to calm down, release melatonin (sleep hormone), they need a short period of time in which you repeat your chosen sleep associations.

Babies will begin – from that very first week – to associate things with sleep.

If you always nurse a baby to sleep, rock a baby to sleep, or lie down with baby to help them go to sleep they will need this. These are called sleep props because they prevent baby from learning how to get to sleep on their own.

Essential elements to a wind down routine include positive sleep associations which are those things that baby associates with sleep that help them calm down and get to sleep on their own.

You may want to print these beautiful wind down routine cards and hang them in your nursery as well.

Read: End Baby’s Witching Hour — In 4 Simple Steps

Wind Down Routine Essentials:

  • Turn down lights so the room is dim.
  • Use your phone app or a machine and turn on white noise.
  • Hold baby in a relatively still and comfortable position so they become calm.
  • Rock, swing, or move gently to help baby get drowsy.
  • Put baby into their own sleep space while drowsy, but still awake.
  • Swaddle baby and then, if desired, offer baby the pacifier.

28 Things To Do If Baby Won’t Sleep CHECKLIST

Fast, simple, and free strategies to implement if baby can’t get to sleep, won’t stay asleep, or is unsettled in general.

All in all, baby bedtime doesn’t have to be such a big battle. It may take a few nights of tweaking your current routine, but I’m confident you can see positive changes in just a few short days.

You can begin making positive changes that take the bedtime from 3 hours of shenanigans to 20 minutes of precious bonding time.

What is a good bedtime for a baby under 1?

Typically, between 6:30 and 7:30 pm is the best time for baby to go to bed. This will help prevent overtiredness and let them take advantage of the deepest time of sleep (before midnight).rnrnWhen babies have missed naps, move bedtime up slightly so they don’t go into the night overtired. When baby is overtired they will release stress hormones that will make it harder to stay asleep.

How do you move a baby’s bedtime up?

If baby is currently going to bed late and you want to move it up until, say, 7 p.m. you can try a few things. You can go cold turkey and move bedtime to 7 p.m. and help settle your little one if they protest.rnrnOr you can move bedtime up in increments. Don’t allow napping past 3:30 p.m. at the latest, and then move bedtime up by 15 or 20 minutes each night until you reach the desired bedtime.

Is 9 pm too late for baby to go to bed?

In general, earlier bedtimes help babies fall asleep more easily and stay asleep longer. Most babies do best with a bedtime between 6:30 and 8:00 p.m. Once they’re overtired, their bodies release cortisol (the “stress hormone”), which makes it harder to fall and stay asleep.

It’s totally fine if your newborn’s longest stretch of night sleep doesn’t start until 9 or even 10 p.m. Most newborns settle into a more consistent (and earlier) bedtime around 6–12 weeks, depending on their unique sleep needs.

What matters more than the time?

  • Making sure your newborn is getting enough total sleep in 24 hours (typically 14–17 hours)

  • Watching wake windows (typically 45–90 minutes)

  • Responding to sleepy cues and allowing plenty of naps during the day

There’s more.

Baby bedtime can begin to feel like an actual nightmare. You just want baby to sleep well.

You just want to have some peace and quiet after a long day of momming and yet you are spending so much time trying to comfort an exhausted baby and wondering where it all went to pot.

Because moms with babies are busy (and tired) I created a set of nitty gritty baby sleep checklists that get straight to the point.
