Other Teacher has a student in her class who is just a tornado. Classic ADHD child, possibly influenced by drugs in pregnancy. Generally a well-meaning boy, but, oh boy. Apparently this week, he pulled out four teeth. Four! How can a child stand to pull out four teeth? Family has noticed similar things.. Now we're wondering if this boy's chaos is due to a very high pain intolerance. He is very rough-and-tumble to trouble, but he possibly may have no source for recognizing he's hurting other kids.
