So my baby had his 2 month shots on Monday. Prior to this, he would poop 2-4 times a day. Since Monday, he has only pooped once on Thursday. Has anyone had this experience? He has been eating the same way he was prior to getting his shots and still has a wet diaper every time I change him (every 2 hours or so), but this is just strange to me that he is not pooping like he was before. I know breastfed babies can go up to 10 days without pooping, but he was so consistent before the shots. He does not seem to be in pain, but I can see him straining and pushing and nothing comes out, and he does seem a lot more gassy than he was before. Any thoughts?
