My mom told me that was normal when my baby was a month and its because they are growing :)

@melody37 we did burp him and he burped a lot. then we usually place him in the care seat which is attached to the stroller. sitting up at that angle usually helps with his hiccups.

Do you hold the baby upright after feeding to burp? Mine did threw up a lot because I didn't let him burp. Also, one burp wasn't enough. He burps twice usually.

This happened to my daughter but it was because i switched her bottle. The one that we used was letting too much air out so we switched back to her original bottle that allows no air in or out and she was back to normal
