3 months ago my son had a typical cold with a dry/scratchy cough. The cold is long gone but he’s retained this constant (and I mean constant, every 10 seconds) clearing of his throat cough-like tick. It’s driving me absolutely mad and I can’t work out how to help him stop. He doesn’t seem to realise he’s even doing it. I’ve asked him to cover his mouth when be coughs in the hope that the action of moving his hand up might make him realise and stop but that’s not working. I’ve tried being patient and also some tough love where I tell him he needs to stop it. I’m at a loss, any tips?
