Has anyone experienced this situation....my baby goes to sleep well after his bottle of formula and then about an hour later he wakes up in pain, screaming and kicking. We try to comfort him and notice that he'll do a big fart and this seems to relax him a little. This has been happening every night for the last week or so, but we noticed it's getting worse. Heard it might be baby reflux, which he has never suffered from before...can anyone help? Thanks!
