Panty liners ???

I have a general question? My daughter is ten and she is turning 11 this year, we’ll all her close friends have started AF and she’s scared she’s Next. She wants to wear panty liners so that if it happens she wouldn’t mess her clothes up, should I let her? I only have one girl this is my first rodeo🤷🏽‍♀️🤷🏽‍♀️
