my 5 year old daughter still sucks her thumb. SHe does it any time she is tired or sometimes bored. I don't mind if she does it at home, but I don't like it when we are out in public (she is tall for her age and looks like a 6 or 7 year old). So, out in public, she can control it if I tell her not to do it. But, at night going to sleep, I just let it be. I've talked to her dentist about it and he said it's fine until she starts to loose her teeth. She just had x rays done at her last exam and she is no where near loosing any teeth soon, so he said it's still ok for now. As long as he is just doing it at night, I wouldn't worry. I don't think he will be 16 and going to sleep overs with his friends and still sucking his thumb. He will grow out of it sometime
