How Much Sleep Is Too Much?

I am not sure if a baby can sleep too much or not. I mean in one stretch. My daughter (3&1/2months) had a rough night last night... neighbors had a party and were very loud until about 11pm. I got her to sleep finally by 9pm (normal bedtime is 7ish) but based on her restlessness I could tell deep sleep didn't come until around 10:30. At around 2:30 when I checked on her her diaper had majorage leak issues again because she had turned over on her tummy (I posted a question a few days back and we are still working on this issue!) I carried her into the living room, changed her outfit and diaper and washed her with a warm washcloth, changed her bedding and put her back to bed all without her waking up. Now it is after 6am and she is still sleeping. I have read a couple books about creating good sleep habits and so far everything I have read says after the 3mo mark, do not wake your baby. Is 9hrs plus of sleep ok for a baby under 4months? She is both breast & bottle fed.

What can I do next?

Lots of babies at that age sleep from 7pm until the next morning ie 12 hrs. Get Dr. Marc Weisblut's "Healthy Sleep Habits, happy baby" and it has good charts on the range of sleep hrs but sleeping 10-12 hrs at a stretch at that age is pretty normal. It is more if they don't that you have to worry and work on it. Good luck.

Let her sleep. She'll wake when she's hungry.

YES! Enjoy it. (In the hospital, one old school doc gave me this tip - she can sleep as many hours as she is in lbs. So a 7 lb baby can sleep 7 hours without worrying.) I'm assuming that your 3 month old is at least 9 lbs, so enjoy the rest!

Babies tend to sleep more when they are getting ready to have a growth spurt or if they've been working on a new milstone. Just let her sleep and let nature take it's course.

I agree - let her sleep! Also, you referenced her rolling onto her tummy. We had the same issue with our daughter (she rolled over early, I thought). Our pediatrician said that if your baby is strong enough to roll onto their stomach, then she was ready for it and that I shouldn't worry about keeping her on her back. It was a relief to not worry when my son started doing the same thing. Good luck and get some rest :)

Hello! My son was breast and bottle fed at that age and slept from 730-630 almost every night without any problems. Assuming that your daughter is doing well with her eating, growing, etc., it is definitely possible that she is taking in enough food to sustain her while she sleeps all night. Good luck!!

Definatly let her sleep!!! I wish my 3 month old slept that good. She will sleep from about 7:30 to around midnight and then is up and restless every our and a half to 2 hours after that. Enjoy the sleep!

I agree...let her sleep. My girls both slept thru the night at 6 weeks. Sometimes that meant 10-11 hours. They also took at least 2 naps at 1-1/2 hours during the day at that age. Sleep is good...especially for babies. She probably isn't getting "good" sleep because of the leaky diaper issue. Be happy she is sleeping, there are some moms on this site that can't get their children to sleep more than a couple of hours at a time. :)

Let her sleep. As long as she is eating and gaining weight, let her sleep!

starting as old as 7 wks old, a baby can sleep up to 12 hours at night and still be fine as long as during the day they are getting the proper amount of nursings/bottles and wet/dirty diapers.

Optimal sleep per 24 hours period is 12 hours at night plus 3 two hour naps for a total sleep of 18 hours, until at least a 8 mos old, then they may drop the last nap down to an hour or out for a total of 16 to 17 hours until at least 17 mos old, then it can drop down to 15 hours until at least 3 yrs old. YEP, that is what I said, fifteen hours every 24 hours until 3 yrs old. Then it may drop down to 14 hours around 4 yrs old, but never below 12 hours until at least 7 yrs old.

Totally normal. My 3 1/2 month old has been sleeping for about 10 hours for the last 2 weeks. My older son at about this age slept from 6:30 to 6:30. Enjoy and get some rest.

Let her sleep. She is so young... sleep actually is very important for development/immune system/brain development.
My son at that age, sleep a lot too... and continues to be a good sleeper and napper.

Just the other week, my son went to nap (because he was tired) at 3:30 in the afternoon... and he didn't wake up until 6:30am the next day. He slept 15 hours! Straight.
He was not sick or anything. And I checked on him constantly just in case. But the next day, it seemed like he grew and was so much more rested. I think he simply needed it and is growing. Again.

all the best,
Susan

Let her sleep. I go by the "never wake a sleeping baby" mantra and it has worked well for us. She will wake when she's hungry and it's good for her to get some solid sleep.
