My baby is 11 months old and has suddenly started to refuse having her teeth brushed. She clamps her lips shut and squirms away. I cannot for love nor money get her to open her mouth once she sees the toothbrush. I bought the same toothbrush as hers and began brushing my teeth in front of her and this made her laugh/let me do it for like 2 days and then stopped working. How do I do this? Is there a trick? Is there another way to get baby's teeth clean? I don't want to create a negative association with it. She has 5 teeth currently.
