Cloth pads

It's nice that you want to adopt eco-friendly practices from young. Considering your girl is the one who will be using the cloth pads, it's important that she knows (1) how to use them, (2) proper storage after changing, to prevent odours (I put my used one in a square Daiso box, and then into a small wet bag which I hang onto my bag with a carabiner--So that I remember to wash it when I get home) Menses can be a stressful event, so you'd want to ensure that she is first, confident to use them at home, before she uses them in school. All the best!
