DD never sucked her thumb as a baby, but when she started preschool she saw some of her friends doing it and started too. It has now become a habit and is impacting her teeth.
To help her to break the habit we have tried paint on treatments, but these come off when she washes her hands. We tried using plasters but they come off. We bought a silicone guard thing online but she can flex her thumb out of it and still suck it.
I don't know what else to try! I'd really it to stop before her adult teeth come in.
