I wouldn't worry about her making contact on your face just don't make a habit of putting her in front of it. Baby's have such a small strike range. She may try but as long as you're not try to kiss her she shouldn't tap you as much as she may try. Right now she just needs time. Patience will be key in this even though it's super exciting to get a new snake and you don't want to leave it alone. I agree with giving her a few meals first.
