Hi J.. Both of my daughters still suck their thumbs and they are 9 and 7. They only suck their thumb when they sleep or are seriously tired. But the serious downfall from that is the morning breath from it. It's horrible. Neither one of them started this habit until they were about 3. I've tried all different methods and it doesn't work. I work for a dentist and he's even tried talking to them and it's not working. I wish you luck and hope you find a solution that works for you.
