My ds is nearly 5 months and still feeds every 3 hours night and day.
He has small amounts (it seems to me, compared to other babies his age) of 3-5oz at each feed. I can't encourage him to eat more during the day; if he doesn't want it, he just won't have it!
Friends have suggested switching the night feeds to water, which might encourage him to eat more in the day and then sleep at night.
Isn't this too young to drop night feeds? I know if he chooses to sleep through, that's a different matter, but if he is still drinking at night perhaps he needs it...? He is on the 25th centile if this has any bearing on anything.
As he's my 4th dc you'd think I'd know better...
