I started using them for my second period casue i couldnt stand using pads. i remember being so self concious when i was wereing a pad when i was younger. I thinki was 13. They make the SO skinny these days. My sister is 14 and she has tried them but wasnt very keen, she is happy to use a pad.

I think it depends on your DD, if she is asking to try them and seems ok with it then id find her some good ones and see how she goes. good luck.
