My nearly 7 month old has always taken over an hour to get back to sleep after a nappy change during the night after he's done a number 2.
He just lies there wide awake tossing and turning until eventually after nearly an hour and a half he falls back asleep. It's becoming exhausting as I like to keep an eye on when he eventually falls back to sleep to make sure he's getting enough night time sleep overall.
Suppose I just want reassurance that this is something that they grow out of? He's done it since newborn so you'd think I'd be used to it by now but he's really not the best sleeper as is so makes it extra exhausting when it happens.
