Hey there hun, we get about 2-4 poops here as well, you might want to check with your pedi if you have any concerns though
I agree with Chicane that he might have been OT day2 may have been OT from day1, so I'm assuming he was up @ 08.45 today & went down @ 11, that's a total of 02.15 A time, which is a little low for his age, but since he's given you a good nap, might be that he was OT & was catching up on lost sleep.
So let's try & follow his cues today, staying @ ard 3 hrs & see how things go. I also agree about the DF, we also dropped it @ around this age, although we kept getting one NW for food, but ds is bf-ed & I know formula fed babies can male it through the night better that bf-ed.
Keep us posted about how things go
Just saw your post, OT : Overtired, NW: Nightwaking
