As we say in my choir (or shout, rather): HAAAAAAAAAAAPPY BIIIIIIIIIIIRTHDAAAAAAAAAAAY!!!

Ooo, ouch... little biting boys can be a pain (in more ways than one). I know because my brother used to bite people when he was angry (myself included). Of course, he's autistic, but still... biting is biting. I hope he overcomes that phase quickly!
