Sour poop?
So my boy started going poop like every 3-4 days instead of daily. We ebf and no solids yet. Dr said it was fine that he goes this often as it doesn't seem to bother him. But when he does go now it's a lot thicker than it used to be- not solid but less watery which I figure is probably normal. It's still yellow but it smells awful now. Like a sour smell and it used to hardly smell at all. Does this happen to anyone else?
He just went again and it is definitely a vinegar smell. So weird.
