DDs upper front teeth came in over Christmas and since then, she has been grinding them against her bottom teeth almost constantly. I have tried saying "no no", picking her up and distracting her but she grinds away regardless. So far giving her cheek a gentle stroke while shaking my head and saying "no" will get her to pause but then she starts again straight away. Is this a common phase she is likely to grow out of? Or are there any other suggestions for how I can get her to stop? Thanks in advance.
