7 Habits Your Tots Need to Break and How to Help Them Do It

Why it's bad: In addition to calluses, blisters, and infections, thumb-suckers run the risk of having misaligned teeth. So unless you want to spend thousands of dollars on braces, we suggest getting the thumb out of their mouth.

How to stop it: If your child sucks their thumb out of boredom, as many do, come up with creative ways to distract them. Art projects or hand-related games are a great place to start.
