Barielle reviews review content.
Anti-Nail Biting Polish DOES NOT WORK for thumb suckers. It is designed for daytime nail biters – and only offers a little reminder. Obviously won’t work while your child is sleeping and their taste buds are turned off. Children under four years old don’t dislike the taste because they haven’t yet developed taste buds to dislike it yet. Nail polish was developed for nails, not thumbs.
