My oldest DD discovered she could comfort herself by sucking her 2 middle fingers when she was just a few months old. We thought it was great. Fast forward 4 years, and it's not so great. She actually seems to be sucking her fingers more often. It's rather frustrating. We've tried taping her fingers, bandaids, bribery, but nothing seems to discourage her. The dentist has commented on her teeth, so that is a concern. Not to mention all the germs that she is constantly ingesting. Anyone have experience with this? Do we just wait it out?

TIA!
