If its not one thing.....
Alfie has now managed to break his other lower incisor! At least I'm pretty sure it's his other one, I'll ring the practice tomorrow and check his notes. I think he must have broken one tooth, they were dead even two days ago and one is now markedly longer than the other, it can't have grown that much in 2 days surely!
It's not affecting him, neither tooth is overgrown just the broken one is shorter, and he's eating fine but now they're probably going to wear unevenly again. Gah!
He obviously just has cr*p teeth! I'd started sprinkling some extra vitamins on his food thinking he might need a boost for his cr*ppy teeth. He won't touch the porridgy baby cereal I got for him because it was high in calcium though
