Hello. My baby will be 3 weeks old on Thursday, and I have had a problem with him spitting up alot the past few days or so. I try to burp him after he eats, but he will either move around so he can get back to the breast or wont burp. My husband can get him to burp, but he's not here during the day. Also, the past few days he has seemed to be having tummy troubles. He will eat and then get really fussy and upset. It seems like maybe his tummy is bothering him and we try to burp him. Sometimes he will burp and feel better. I don't know if it is something I am eating or what is going on. I just don't know what to do!
