Excessive wind

So long story short… my dd (9 weeks) has had trouble burping since she was born. She is cows milk intolerant and was breastfed. I stopped all dairy which helped a little but not fully so we switched to Nutramigin. This has helped the gas and poo side of things immensely but now im left with an extemely windy baby. I burp all through her feeds (shes only on 4ounces wnd i burp every ounce) which comes up easily. But after she is done sometimes i can get up to 10-15 burps afterwards. I will get a big burp and she will seem settled but not even a minute later she’s squirming with another burp. Through the night is hellish as its taking me sometimes 3 hours before she will settle and stay asleep. As soon as i lay her down she has yet another burp. I was using mam bottles and have now changed to Dr brown bottles which helps takes the burps up while feeding so easily… its just after the feeding is done😭 im at my wits end and feel so sorry for the little one not being able to rest properly
