Awww, poor baby

And your poor nose
Does she have stitches or staples? If so, then you have to wait until 48 hours or so after they are removed (they leave tiny microscopic holes when removed so they need to close up) If they used surgical glue, you can bathe her now, just don't scrub that area or let it soak in the water. You may want to wait a day or so anyway, just because she's probably very sore and tender and I'm sure getting washed would just make her feel worse. Baby wipes to the rescue
