My dd is now 5 months and still suffers terrible with wind! She is on special milk due to intolerance, has ranitidine, gaviscon and bottles of gripe water but nothing seems to work! When she gets wind she will scream inconsolably until she burps, she only manages 3-4 oz each feed before it starts...any tips on how to help? I feel so helpless and I'm sure she is hungry just can't get her milk down
