My boy is just over 12 weeks and was sleeping through the night (from 9.30 until about 6.30-7), but this week he has been woken through the night and the last 3 for a feed. Is this normal for this stage? Do they have a growth spurt around now?

Your baby previous to now was unusual. He is now behaving in a more 'normal' way. It's unlikely a growth spurt as such, probably more that he is a growing baby with a tiny stomach, and even though he has previously slept for long periods, that doesn't mean he is capable of sustaining that indefinitely. Its actually most common for a baby of his age to need 2-3 night feeds, so you are still doing 'well'! At around 4 months, sleep can be interrupted quite dramatically as they go through a well documented '4 month sleep regression'. The worst offenders wake hourly, and this phase can last about 3-4 weeks. This is also normal. Don't despair if it happens to you.... it will get better, and by six months, you can start helping your baby sleep through the night without feeds if this is what you want.

But do not deny your baby food overnight until he is at least six months old AND well established on solids. If he is waking for food, its because he needs it.

My boy sounds very similar to yours - he has been sleeping from about 7pm to 6am for the past 4 weeks but at about the 12 week mark he woke during the night at about 1am. He did it for about 4 nights and each time I gave him a bottle and he drank the full thing! He also seemed hungrier during the day and fed more than normal too. He has returned to his previous ways now though and is back to not waking.

I agree though, we are definitely blessed with good sleepers as I think it's very unusual to have sleep patterns like we both seem to have. I'm not going to question it but just to be grateful for it as I know how quickly it can change! I also have a 4yo DD and she rarely sleeps through the night, ha!

My baby was sleeping 9:30-5ish, 12 weeks this week he has woken earlier for an extra feed all week. My 3 yo dd slept through from 6-12 weeks and never again after that until after 2 years old. In my experience it has been an age for sleep regression.

Thanks guys. I didn't think it was too unusual that he slept overnight, I thought I was just lucky, and seeing as though he isn't a great day sleeper. He would usually cluster feed at night before going down and a hungry baby wont sleep. I have never denied him a feed if he wakes and doesn't settle, then I know he is hungry. It's just that he has woken during the night before because it has been cold and once I've added an extra blanket he has gone back to sleep until the morning.
He is also wanting more feeds during the day so I'm hoping that it is a growth spurt & he will settle back down soon, otherwise I have to prepare myself for the interrupted sleep again!
Thanks again.
