My dd is 10.5 months and has severe wind at night... tummy full of bubbles... lots of crying and tears. I have tried so many products, nothing helps. She is breastfed (still doing around 3 feeds a day). Have tried colief, a few months ago now, but it didnt seem to help... So is it lactose intolerance or not? Is it less common if breastfed? Can she be tested for it? Can lactose intolerance come and go? (in the sense that sometimes shes fine, no probs at all... others she's terrible and wakes all through the night). Any opinions would be a help. thanks.
