Hello hoping someone can help! My 7 year old son has an itchy tongue now and again. He is otherwise healthy. I've checked his tongue and can't see anything obvious. I know babies are susceptible to oral thrush but don't often hear older children suffering from it. Does anyone else's older child also suffer from oral thrush or itchy tongue. We're not sure what it is...just very frustrating. Will be booking a GP appointment after the weekend.
