My little boy is going through the great four month sleep "regression" and has gone from waking once a night to twice, then gettin up ridiculously early. That's fine, I am not bothered about getting up with him. What I am wondering is, is he getting enough sleep? He probably gets around 10 hours all up at night, and every day he takes thre naps lasting between an hour and an hour and a half. He doesnt seem too grumpy but it is said that babies of his age should get 16 hours, and he is getting arund 13.
He is also off his food a bit, seems to eat less at each feed but want to be fed more often (he is on formula). Is this a usual part of the four month stuff???
