Oh another thing I just thought of, how is your letdown? Supply? I had oversupply and a powerful letdown with DS which can cause wind. I've heard the foremilk can make for reflux and wind so I did block feeding which did help a lot. I would feed from the one side any time bub wanted to feed in a four hr block so that he was getting the creamy hind milk which wasn't so wind inducing and then swap to the other side for the next four hour block. If you have a powerful letdown you could hand express a little when letdown occurs so that bub isn't having to gulp a lot, taking in more air. Smaller feeds more often can help with reflux and elevating the head end of the bed.
