DD's top two teeth broke through in the last week and she has started grinding her teeth while she's awake (I've not heard her do it in her sleep). Today she's been quite obviously struggling with some sort of teething pain (wants to nurse/is clingy/chewing everything like mad/somewhat relieved by teething drops), but she's also been doing it on days where I wouldn't suspect her to be in discomfort based on her behaviour. The noise goes through me and of course this isn't going to be good for her teeth! I have no idea if this is her exploring the sensation of now having top and bottom teeth or what, but moreso whether it's normal. Anyone else?
