I would try to keep them trimmed and filed (trim every few days and file every night) so there is nothing to chew, and wash her hands frequently. Unfortunately, she might be a nail biter (my husband is and always has been--nasty!). If you minimize what she can bite and offer her teething and biting toys, she might cut back. Good luck! (And you're right--no reason to get mad at her at that age. Try pulling her nails out of her mouth and telling her "yucky" and putting something else in her hands.)
