Nail varnish to help stop thumb sucking

If your dentist is giving you the condescending lecture about thumb sucking and adult tooth growth, Mavala Stop may help your child break the habit.

The nail polish has been created specifically to be worn by thumb sucking children to leave a toxin free but bitter taste in the mouth to discourage the habit.

A thin layer of the formula is applied to the thumb or fingers and refreshed every two days.

Available from John Lewis £5 as well as other online retailers
