He's not my first child to take a bite, but it got me thinking about the differences in my kids. It's not that I haven't told Big before..."Crayons are not for eating, Big" or "Crayons do not go in your mouth, Big". But, he seems to be one of those kids who has to find out for himself whether crayons are for eating or not (for the record, when I asked him how the crayon tasted, he said, "good". When I said "Really?!", he said, "No... yucky").
I have a couple of kids who took my word for it not to eat the crayons, play doh, glue, etc. And I have a couple who have to try it out before they figure it out. I should make note of this before the teenage years come along.
