My baby is 5 and a half months nearly 6 months. At the start he had colic and then HV said he was allergic to dairy. He was on cow and gate at the start then had to go onto neocate special milk. Recently we started the home challenge to see how he tolerates Cow and gate and dairy and I've noticed these tiny tiny spots on mouth and belly. He is teething also could it be teething spots or does it look like reaction to milk and dairy.
