We use Target as well. I would suggest maybe going up a size also. IMO I also think it's weird that your daycare makes him stay home just for blowouts? If it's diarreah that's one thing but not for regular poop.
Yeah, they call all liquid poops that escape the diaper diarrhea. His still mostly breastfed and therefore on a liquid diet. You aren't going to get all that solid of a poop out of him until there are more solids. Can't wait till LO starts liking solids more.
Anyway, thank you for the suggestion of moving up a size. I hadn't thought of that as I have been just going by the weight suggestions on the box and size 4 looked so big!
