DS2 (11 MONTHS)has got a pale patch on the roof of his mouth. It's kind of hard to explain but its like he has been upside-down and some kind of pale liquid has been poured into his mouth which has pooled in the roof of his mouth and gone hard (crazy explaination I know LOL).Shown it to my SIL who is a nurse and has had a gazillion 4 kids and she says she's never seen anything like it. Def not thrush and not bothering his as such unless you try and touch it but that could just be an objection to Mummy sticking he fingers in his mouth LOL! Any ideas?
