DD age 13 just started 2nd period and it's looking increasingly likely she might have one while on watersports holiday with friends in a couple of months. Not sure how to help her prepare for and deal with this. Suggest she tries tampons now? I've seen period swimwear exists but don't understand how it works...doesn't it just absorb water? And it would surely take ages to dry but she'll be in a swimsuit loads. I'm thinking I need to get her to try tampons asap...this had not occurred to me when we booked aaaages ago.
