Does anyone know what this rash could be?

My daughter has had this rash for about 2 weeks now! I’ve been to the doctors twice and they’ve both said it’s nothing to worry about. As it goes away when you press on it. She’s not even noticed it’s there and she’s still eating well and is fine in herself. But It seems to be getting worse and spreading more?
