Non-toxic Chalk

I love sidewalk chalk and Lincoln loves it too! I like to draw on the cement and he likes to eat it. I checked the label and was glad that it was non-toxic. I tasted it to check out the appeal but it really had no flavor; didn't even taste chalky! So today when I decided to pull out the sidewalk chalk with Lincoln for the first time, I might have been a bit too rushed. He did make a few lines on the cement but more often it was in his mouth. I think we will wait till Spring to try again.
