I’ve known a few people use their middle names over my lifetime. You don’t have to do anything legal, just call her what she wants, just sticking to her registered name for legal stuff, as henetha said.
Once she’s 18, she can change it herself if it bothers her that much. The danger now is changing it, then her wanting to go back in a year! Depending on which way the wind is blowing.
