My 10 year old wets the bed every night "on purpose"?

Wetting the bed on purpose or not, to me its pretty simple. Diaper her at night. If she wants to wet the bed she can wet the diapers and save the bedding. If she is really having accidents then again diapers will protect the bedding and she wont wake up in nasty wet sheet. Put her in diapers, saves you laundry and saves the bedding. Pampers size 7 diapers might fit her or there are youth diapers from secure plus or bambino diapers.
