While kicking a habit like nail bitting or toy chewing is not as simple as giving a child Chewlery, the pendant can be a great practical tool to reduce power struggle and stress surrounding these habits which can actually make it worse. I find that the Chewlery can be a great tool for children that are dealing with a soothing habit like biting nails or twirling hair, IF the efforts to kick such habits are going to be combined with ways to really address the underlying cause as well.
