ds is 10 months. he's got six teeth and i think a couple more on the way.
over the last couple of weeks he has started grinding his teeth (when cross, when tired, when playing, when feeling like grinding his teeth a bit). i absolutely hate the noise (think fingernails on blackboards) but saying no doesn't seem to help.
i'm not even sure he knows he's doing it.
any advice (or failing that, people to tell me it's a very, very short phase that they go through)?
