DD2 is exclusively fed EBM and the nurses have commented on how windy she is. What causes wind in a BF* baby? They said she is the windiest baby on the ward and also the hardest baby they've ever had to burp. Basically they can't make her burp and she builds up a lot of gas before farting it out hours later. At the moment it is getting in the way of her feeding because she refuses to swallow when she has wind pain. Any ideas? Am I eating the wrong thing? Is there something wrong with my BM?

*I am not sure if she is technically "BF" or not. But she gets only BM, delivered either by her ng tube (no air involved) or by a bottle.
