I've noticed a couple of white spots on the tongue of 2 month old DS. They been there for a couple of days and don't seem to wipe away with my finger so I'm wondering if it could be thrush. There's been no change in feeding and no pain for me but I'm wondering if I should get it checked out to try to preempt any problems? The thing is that the spots are quite far back on his tongue so it could be tricky for anyone else to get a look!
