Query: Teethers beware splinters.

My kid mostly played with the cars as though they were cars. He did some shape matching for a few minutes, but would get bored with that pretty quickly. My biggest problem was pulling the splinter out of his lip after he gnawed on one of the puzzle pieces.I'm having the same splinter problem with the wooden ABC blocks. Funny -- I don't remember that being a problem when I was a kid.
