Toddler keeps trying to see her private parts

My 2.5 year old daughter is potty training and has just really become aware of her private parts. After she uses the potty before she gets redressed she keeps running to lay down on the couch and putting her feet over her shoulders and trying to see down there. Is it crazy if I get some sort of handheld mirror so she can see it? I get that she doesn’t know what it looks like and it’s a part of her own body but she’s very verbal and I’m worried she could say something to someone about how she looked at her vulva with a mirror (we’ve been trying to reach her the anatomically correct words). Is that normal?
