Thought it was impetigo but it's gone on for a month, hasn't spread and is where he has his tongue hanging out! When he's a bit nervous or shy he puts his tongue out and it's always in that spot. I've been sneaking bepanthan cream on it once he's asleep but he won't let me put anything on it in the day. What can I do? I don't know how to make it better as he won't put his tongue away! It's not constant obviously but enough that now it's sore it won't get better. Does he need doctor for a stronger cream?
