DD2 is coming up for 2 years old and looking back I think she is milk intolerant. She was feed EBM for the first 6 months then put on formula which is when she started getting terrible nappy rash. She never drank more 4ozs at a time and didn't sleep well but we managed (and didn't think to blame the milk). At 18 months I stopped allowing her to use a teat and she then refused to drink milk which soon after the rash disappeared. She still has yoghurt & cheese so is getting some calcium but I've noticed recently that if she has too much it makes her sick at night and her sores return, we live in a hard water area so that contains some calcium too but what elsed is there?
