Well one side looks a little larger but probably the way he’s laying it the way u took the pic but as for being big and round yes they always have big round belly’s my 8 month old still has one a lot less pronounced then it was before!
Looks normal to me, my baby’s tummy was like that until he started fattening up.
@bossmamax2, it might just be that. Babies always look bloated but if he’s not fussy then it’s normal
It’s probably the way he’s laying, and a little bloated which they get after eating or have gas. But it looks normal.
