Are thumb guards effective at stopping thumb-sucking?

Maybe: Only way to know is to "buy and try." but is it really that much a problem to go that far? Maybe there is an underlying reason for the thumb-sucking you have not explored yet. Is it more frequent when they come home from daycare or a friends house or etc?

Thumb guards: I think that if a kid wants to suck his or her thumb , they will find a way to get to it and get the thumb guard off. Good luck with that problem. Dr brazelton is a famous. Pediatrician i used to look up to help with these problems or any sleep issues. Good luck.
