Snuggle Bunny

For Christmas, Grandma Winn made sock bunnies for each of the girls. Kairi enjoyed hers, but her sister loves it more. And not only one bunny- both bunnies. Kesslynn has confiscated them both, stripped them nude and she carries it around sucking on the arms, legs, or ears. It is very funny to watch, but she uses it as a comfort measure. She will walk around the house with this bunny hanging out of her mouth. Now my big concern is how do I wash them?
