Overnight diaper?

la79al

DD2 is potty trained 95% of the time but she also ends up in my bed 95% of the nights so I'm not ready for her to go diaperless.  I am looking for some kind of diaper that she can wear and we can wash.  Right now she wears regular diapers and they work fine except she can go a week without peeing in them and it feels stupid to throw away dry diapers.  Even if we reuse them, after a few days they start to fall apart. Any ideas?
