My two week old gets really bad wind. It mostly doesn't bother her too much and when it does it doesn't take too long o sort. The problem is that she's a terrible sleeper and I know it's her tummy waking her up. Ill feed her,burp her, hour later down for nap. She sleeps so fitfully and every time she wakes I can hear its her tummy or farts. Then has to be resettled every ten mins or so. I'm reluctant to try infacol because its not like she's in agony, although she is getting very overtired and fractious. But maybe it would help?
