I think I used to suck on ice when I was cutting teeth.

I have to say, it may be hell to go through teething, but I was over at a friend's house and playing with her adorable son, who decided that my fingers were some kind of chew toy, and I got to (painfully) discover his first tooth. It was an oddly humbling and amazing experience.
"For I have known them all already, known them all -
Have known the evenings, mornings, afternoons,
I have measured out my life with coffee spoons."
