My baby is 4 months old today and up until this point he never burped too much or spit up at all.

But this week he has to take breaks while feeding and burps like a grown man lol. And then he’s started to spit up . Is this ok? Should I change something in my diet?

He also isn’t eating as often. Maybe he got better at getting the milk out but it’s hard to get him to feed over 20 min. He only wants to eat like 10 min on one side and 5 min the other usually.
