DD and I had a girls night last night with a movie-thon and popcorn as DH was away and younger DD at a sleepover. Afterwards, just for fun, she asked to sleep in my bed, which I didn't mind. I went to bed about an hour after her. Boy is she noisy!! I am not sure it is teeth grinding as such, as it's not really a squeaking/grinding but more a sort of wierd clicking/grunting sort of noise. The dentist has never said anything but she is due to see her soon and I think I will ask if it is affecting her teeth. It's a bit irritating to be honest. I found myself thinking that when she is older and spends the night with a boyfriend they are going to find it very annoying! Anyone else's child do this?
