Negative Positive
Title: Worked for a few minutes...
Review: My 3.5yr old is a chronic thumb sucker. Orthodontist recommended based on results from other patients. My son said it tasted yucky and wouldn't suck his thumb for an hour or so but then he just didn't seem to care after that. But he's stubborn. Seems to work for a lot of other people and I'm thinking about trying with my older son to stop nail biting.
Is the review positive or negative?
