My 7yr old DS started developing some nervous habits around a year ago. It started as twitching his shoulders but progressed to pulling at his waistband - he says that sometimes in bed he has to do it “a thousand times”. He also clears his throat and it happens more if he watching the iPad or tv. This drives me & my DH crazy as sometimes he does it constantly - I thought there was something wrong with his throat (there isn’t) but he says he “needs” to do it. To add to things, recently he has started smelling his fingers and again it’s compulsive and he needs to do it. I worry about this one in case he’s doing it at school.
I’ve read that these are things he’ll grow out of but I’m wondering if there is anything I should/could be doing or signs I should be looking for? He’s a sensitive boy but I don’t consider him to be anxious.
