Don't worry. He's still chubby.

Today was another bath day with Max. He enjoyed it immensely, then enjoyed a good cuddle with Dad.  He got weighed and came in at 4120g (9lbs 1oz) which means he's gaining a bit less per day now. They've decreased the size of his feeds for a few reasons. For one thing, he wasn't always keeping everything down.  Most likely, they were increasing it too quickly before, so they're pacing it differently now. Another thing is that he may want to breastfeed more if he is a bit hungrier between feeds.  They're not starving him by any means, but this may simply trigger a stronger feed craving in the chubby guy.  Hopefully, it helps and he can progress even faster at the whole feeding thing.
