Chalk
So... just how non-toxic is chalk? I ask because I have a three year old who loves his chalkboard and a ten month old who is teething. You can see the problem. We've tried to get Jaden to keep his chalk on a special spot on the bookshelf, but so far that isn't working out too well. I'm wondering if I need to just take the whole thing away for a few months, or if the occasional teething on the chalk until I catch him at it isn't really a big deal.
