My 3 year old still wets at night, too. She's also a heavy wetter and I have yet to find a cloth solution for her, so she's in disposable pull ups.
My 1 year old is also in disposable diapers at night. He, too is a heavy wetter, and sometimes soaks through his sposies.
I have two problems with cloth diapering at night:
1. Not enough absorption for my heavy wetters.
2. They sleep for 12 hours. That's a long time to have urine-soaked fabric against their skin. My 1 year old gets red and irritated after 2-3 hours in a cloth diaper, let alone 12!
I would still like to figure out a way to cloth them at night. I'm thinking a liner of a mesh material....like a barrier between skin and the urine soaked cloth underneathe....would be the way go. Now, if I can just figure absorption.
Any ideas? Tricks of the trade?
