She actually bit my sister. My sister wanted to get bitten for some reason, and it happened while she was holding her. She said it didn't feel like much, but the baby hatched on August 3rd, so I'm assuming she can't do much damage. I'm more worried about being surprised by it and accidentally jerking my hand. I've got a 2-3 year old female, but she's never bitten, and is generally calm. I'm just concerned with getting the baby used to handling.
