Suggest Remedy For Swollen, Itchy And Red Belly Button In A Child

Hello. My daughter, 9 years old, said her Belly Button itches. So I looked at it and its red and looks a tiny bit swollen. That was about 5 hours ago after school. Then we came home, I put some essential oils around it to help the itching. She had ballet earlier this evening and she came out and said during class it felt ok, but once she changed, it s bothering her again. Came home, put some anti itch cream around it…. but now I m looking up possibilites… She s 9. Very active. No known health issues.
