Q&A: 4-month wakeful period?

I've heard that babies can have a wakeful period at around four months, where a baby who's been sleeping fine all of a sudden starts waking during the month. Why does this happen, and how should I deal with it?

Re: I've heard that babies can have a wakeful period at around four months, where a baby who's been sleeping fine all of a sudden starts waking during the month. Why does this happen, and how should I deal with it?

The Bump Expert

It's not uncommon for babies to start having sleep difficulties around their four-month birthday. This ages marks a huge cognitive and emotional turning point for babies, as they become much more aware of -- and interested in -- the world around them. It can also mean they'll sometimes want to play during the night. This is actually a good sign, because it means baby is bonding with you and having a good time during the day. However, it's challenging to cater to his desire to be with you around the clock.

So, that's why the wakeful period happens. Now, what can you do about it? If you're up for sleep training, now is a good time to start. Pick an approach that you and your partner both believe in so that you can support each other through the sleep teaching process. Start when your baby is healthy and when he'll be sleeping at home for a couple of weeks.

If you're not interested in sleep training or just not ready yet, our advice is to be minimally invasive at night. When you go in, try to soothe your baby without picking him up. If you feel your baby needs to be fed, give him enough to satisfy him but not fill up his entire stomach. While these things may not get him to sleep straight through the night, they are good baby steps toward encouraging him to become an independent sleeper.

re: Q: 4-month wakeful period?

If you exclusively breastfeed this increased interest in surroundings will also mean baby is distracted and may not nurse well during the day. So if baby was previously sleeping through the night and now wakes up - he/she may really be hungry! See if baby is really eating when you offer to nurse if just trying to soothe back to sleep doesn't work. Also, try nursing somewhere dark and quiet during the day to cut back on distractions.

Q&A: 4-month wakeful period?

Actually this is a question. When you say "they wake up" through the night. Are they just waking up and content, or are they waking up and crying? LO is 3 months old and the 4 month mark is soon approaching!

Q&A: 4-month wakeful period?

Our little boy is 15 weeks and was sleeping through the night until about a week ago. He is back to waking up every 1-2 hours. He is a breastfed baby (primarily). I have been told by several people that we should just let him cry it out. I don't feel that this is the best approach. I have tried to go in and soothe him but nothing really works except to feed him. The real problem is that he doesn't want to go back into his crib and about the only way WE get any sleep is if we put him in the swing. I usually try 3 times to get him back down before giving up and putting him down in his swing. He will be completely asleep and when I lay him in his crib and quietly leave, hes screaming again. Any suggestions on how to get him to go back to sleep in his crib?

Q&A: 4-month wakeful period?

We are having the same problem with our little one, who is four months old. You just have to wait it out. Keep trying to put them in the crib...eventually they will either fall asleep in there, or you take him out to the swing. There have been times where I have spent 4-5 nights in a row on the couch while my baby sleeps in his swing. You can move the swing to his room, or if he has a bouncy chair or a smaller swing, try putting it into the crib at night with him in it. They can sleep that way, and at least he is still in his crib.

Q&A: 4-month wakeful period?

We went through this at exactly four months. Our daughter was waking up screaming several times during the night because she was rolling in her crib and would get frustrated or stuck. I would just go in and rock her or feed her until she went back to sleep. Fortunately this disruption only lasted about two weeks or so. Since she has gotten used to rolling, she can now fall back asleep on her tummy and sleep through the night.

Q&A: 4-month wakeful period?

This is happening with my daughter now that she is in her 4th month, only it is happening during the day. What used to be a 3 hour nap in the afternoon which would let me get everything done in the house that I needed to get done, has turned into a short cap nap once or twice during the day. Hopefully she will go back to her long naps again soon!

Thank god it's not just me! LoL... I thought maybe it was the transition from me going back to work? No offense to everybody, but I'm glad that you are all going through it too! LoL. At least I know it's normal...

Q&A: 4-month wakeful period?

It's also possible that your baby is starting to teethe. Our 3 1/2 month old is getting her top front teeth and she has been waking up during the night gnawing on her fingers and just otherwise upset. I've been rocking her on my lap but with her facing away from me so it's easy to put her back into the crib without disturbing her.

Q&A: 4-month wakeful period?

our baby isnt waking up in the night just at the crack of dawn any ideas on how to get her to sleep later? I shouldnt complain she sleeps from about 930-630 or 7 but that is early for me!

jesslambert06 | September 17 , 2009 12:21 PM

Q&A: 4-month wakeful period?

my four month old has started waking up at 3:30am, but thankfully she doesn't cry--instead she talks to her mobile. Sometimes she gets herself back to sleep, and there are a few times when she decides she's hungry instead.

Q&A: 4-month wakeful period?

i am so glad to hear that i am not the only one having this problem. my 15 week old started doing the same things that have already been described about a week ago. im so glad to know that its normal. she's also teething which makes her wake way more often.

ty's momma | September 23 , 2009 3:23 PM

Q&A: 4-month wakeful period?

OMG I thought something was wrong with my son. He takes quick 15min naps instead of the 3 hours he used to take. And he used to sleep from 10pm- 6am. Now he wakes arouns 3am. So glad to know this is common.

Q&A: 4-month wakeful period?

oh thank God this was included in my 18 week email!! my baby girl went from sleeping through the night in her bassinet to all of a sudden waking up almost every 3 hours again and will ONLY sleep in her swing! i was so confused trying to figure out what i was doing wrong that changed her sleep habits so dramatically! like a lot of the babies here, i believe she is teething as well! she is constantly chewing and sucking on her hand and most any toy i give her. does anyone know how long this "wakeful period" lasts? we've tried the sleep training, but she just cries and cries until someone comes in and gets her. we have tried to just let her cry, but it seems that she could cry for hours if we let her, and that only gets her more worked up and less able to fall asleep. but i also worry that i am making it more of a habit by going in and "rescuing" her everytime she cries. im at a loss as to how to balance this whole sleeping thing!

preggiewright | September 28 , 2009 1:39 PM

Q&A: 4-month wakeful period?

Babies also go through a growth spurt around four months, so sometimes they are waking up because they are hungry- my daughter started waking up at 3am at 14 weeks after two solid months of 8pm-6am nights, and it was because she's hungry. We've gotten passed the growth spurt but have increased her feedings during the day. On the flip-side, she doesn't nap more than an hour or so during the day, which means 7pm is not a fun time... Good luck!

Q&A: 4-month wakeful period?

Hi everyone I'm new to "the bump" message board. Although I used all of the advice/suggestions during my pregnancy.....it seems like now I have so many more questions since my son has been born. My question is sort of on this same topic "4 month wakeful period." My son is turning 4 months next week (already can't believe it!) He was born 5 weeks premature and ever since we took him home from the hospital has refused to sleep in anything but his carseat! It took me a long time to get used to it but now that he's sleeping the night it's great to get some rest! I talked to his pediatrician about transitioning him into his crib and he just said to do it slowly by putting him in his crib during the day. I've been doing this a little each day and he finally fell asleep for @ 15 minutes yesterday on his own but then wakes up screaming and flailing his arms. I then put him back in his swing and he sleeps for @ an hour. I don't know how long it's going to take to finally get him to sleep in his crib at night but my biggest concern is that I'm going to end up with a one year old that still sleeps in his carseat! Any suggestions or tips as to how I can transition him?

I would check out Baby Whisperer.com! Their method of sleep training is amazing and helps through all these normal baby sleep issues!

Q&A: 4-month wakeful period?

My 15 week old has also started waking up at some time between 2 am and 3 am. And I think he is going through a growth spurt. He wakes up hungry and once we feed him he goes right back to sleep. We don't feed him a whole bottle, maybe 2 ounces. I guess we should try to feed him more during the day. He doesn't take very long naps. He's a cat napper. He never really took long naps. But has always been a good sleeper at night.

ash138 | December 21 , 2009 3:18 PM

Q&A: 4-month wakeful period?

for tarac719: you may want to try one of those swaddle me things so your baby doesn't end up flailing his arms and legs. The carseat is probably comforting for him because it is similar to the womb and he can't move around as much as if he were in his crib. Babies like close quarters.

ash138 | December 21 , 2009 3:21 PM

Q&A: 4-month wakeful period?

We have been having this problem too and found that the swaddling works great, but also using the head cradle inserts for the car seat (the soft u-shaped pillow) placed in the crib and then put the baby's head in it. The baby is still falt but this makes them feel sort of like they're in their car seat!

paigecaroline | December 22 , 2009 2:28 PM

Q&A: 4-month wakeful period?

Tarac- I don't know if you've tried this, but it worked for my husband and I. My son loves his carseat too...the second you put him in he's asleep. The crib was a different story. Even though he's only 8 weeks he sleeps straight through the night, usually from about 9 or 10pm - 7 or 8am. (today it's 8:30am and he's still sleeping!) We found that he likes the carseat becuase he's snug in there, he can't move all around. So what we do in the crib is swaddle him real tight....he loves it! So every night, we swaddle him, lay him in the crib, turn on his mobile and leave him alone. We stay in his room until he's asleep because he's still so small, but usually he'll put him self right to sleep. If he doesn't we simply put his pacifier in his mouth, and shhh shhh him to sleep, if he's throwing his feet around then we just gently hold them down becuase that's what keeps him up. The first time we tried this it took a couple hours so you can't give up. Now, about 4 weeks later, it takes us 5 - 10min. And every night at around the same time we go through the same routine. So he knows when he's swaddled it's time for bed! Good Luck!!!

Q&A: 4-month wakeful period?

My daughter was waking up every night at about 1 a.m. and then would wake up every hour on the hour after that luckily all I had to do was go back in there and give her her pacifier and she would go back down but it was still hard for me to go back to sleep afterwards wondering if she was going to cry again. I talked to my doctor about it and he told me what i was doing was fine but told me not to feed her. She finally stopped this and now only wakes up one time in the middle of the night.

Q&A: 4-month wakeful period?

My mother in law said she experienced this wakeful time with both her kids and the only thing that worked for her was the introduction of cereal at dinner to keep some food in the tummy through the night. I know things were done a lot differently 35 years ago but maybe its worth asking the doc about!

acrlyhed | February 15 , 2010 2:53 PM

Q&A: 4-month wakeful period?

Wow... I thought something was wrong with my little guy... he sleeps through the night but the last two days he has refused to take his daytime naps even though he is so tired.. It takes me an hour to get him down and then he only sleeps for 40 minutes where I used to just plop him in the crib and he would sleep for 1hr 3 times a day.... hopefully this passes..

Pumpkin1030 | March 09 , 2010 7:50 PM

Q&A: 4-month wakeful period?

My experience with 3 kids... It changes and changes and changes. One of my kids was a great sleeper at 6-weeks (like, 6 hours at a shot!), and we thought we had it made. Then everything changed for a couple of months, and she would only sleep for 2-3 hours at a time. No idea why. But it was the same for all the kids. Just when you think you're out of the dark and have them on a schedule, the baby gets a new idea. Good luck to us all!

Q&A: 4-month wakeful period?

I'm ready for my bean to sleep through the night. He did it one time two weeks ago and not since. He is up usually around midnight or one am and again around 5am. I haven't had more than 4 straight hours of sleep since my 3rd month of pregnancy. It is amazing how little sleep one actually needs. Though I miss it!

Q&A: 4-month wakeful period?

i do not believe in letting babies cry it out at all. my son is almost 4 months and has already passed this stage he was 2 months old when it started. it drove me crazy...but i will say if u start getting them on a schedule early and when they do start to go through their wake period try giving them a warm bath even if they have already had one it was the only thing that worked with our son...

red.silver | May 07 , 2010 3:11 AM

Q&A: 4-month wakeful period?

Make sure that your baby is getting enough in their tummy before going to bed. I found that most of the time when one of my kids would start this trend it was time to adjust their feeding amounts and schedule a little bit. Everyone knows that babies and adults alike sleep best on a full stomach =)

racquelcorrea | June 06 , 2010 12:32 AM

Q&A: 4-month wakeful period?

My daughter is going through this now. I run up and down the steeps for 2-3 hours every 10-30 mins then after about 3 hours give up and put her in bed with me to sleep. She takes naps in her swing. I don't believe in the CIO method. I try to soothe her sometimes it works but she normally ends up in bed. How long till this passes?

beau2ful | June 21 , 2010 12:35 PM

wow! great to know I'm not alone. My 4month old baby girl went from sleeping from 11pm-730am straight to ,well, now she wakes up at 4am, nurse for 15 mins and then fall back to sleep til 7 or 8am, OR..lol...she'll stay up for an hour and just talk (babbling) ,nurse a little after her speech,lol, and then fall back to sleep. I'm hoping all this will change after she starts eating solids.

So glad to hear others have started teething early! My little one is just over 3 months and my husband and I are convinced she is teething, she has almost every sign. Startig to affect her sleeping at night too. everyone keeps telling me shes so young to be teething, so I am glad ot hear we aren't alone!

patty2bstela | July 06 , 2010 9:12 AM

Q&A: 4-month wakeful period?

I have read and heard that keeping a baby n a swing or bouncy seat or anything other than the crib at night for a long period of time is not good for their backs. It doesn't allow the spinal cord to grow straight but curved.

VBerden24 | July 06 , 2010 10:48 AM

Q&A: 4-month wakeful period?

I strongly recomend the book "Babywise" Very helpful and was recommended to me by at least 5 families who say that the methods in the book helped them to get their children to sleep through the night. I am half way through the book and my son is only 2 weeks old, so I don't have any first hand success with this book yet. I will let you know how it goes!

All of you mommys that have babies that love their carseat.......how did that happen? My son hates his! I feel so guilty when we have to leave the house because he will cry when he is in it :(

Q&A: 4-month wakeful period?

I'm new to the bump....and it's amazing that the first time I came on here, recommended by my sister-in-law, the issue I've been having was right on the main page... My daughter slept through the night (8 - 9.5 hours) from the time she was four weeks old. When she was 15 weeks, she started eating every 2 hours during the day (primarily breastfed) and every 2 hours at night....for 30 - 40 minutes at a time!!! She drools a ton now and I think she is teething as well, but she is legitimately hungry, eats seriously, and does not spit up hardly at all.... I have been trying to figure out what I've been doing wrong since she slept through the night for so long and now is up every two hours. She's been watching us eat closely for the last four weeks so I've been doing cereal and baby food now. Yesterday she ate 3 bowls of cereal, 1/2 thing of apples, 160 minutes of breastmilk, 8 ounces of formula, and still was up every two hours last night to eat 30-40 minutes each time. She falls back asleep easily and sleeps in her crib no problem, but it is exhausting and frustrating when she used to sleep for so long. I have tried to let her cry, but she cries for 30+ minutes and then when I try to calm her or feed her, she is so worked up that she won't eat and it takes forever to soothe her. I hate to give in to her every time, but she is seriously hungry and eats well and then sleeps again. I hope this period ends soon!!! Has anyone been through this long enough to have any idea how long this lasts?
