My two year old daughter drools quite badly and this is concerning me despite it probably be down to teething. She has 16 teeth out of 20 and is due to turn 3 in December. Her birth mother suffers from Schitzophrenia and was being treated with Sodium Valproate during her pregnancy. We have been advised that this could affect my daughter in later life. I have read various things on the Internet and have found various causes to do with enlarged tonsils, tongue and also the antenoids. Can anyone please advise? Thanks Ewan
