Big news: Benny went pee in the toilet last night. And, unlike the other times he's gone to the bathroom on the big boy chair, he seemed to understand what was going on last night and was excited to be doing it. I'm not sure if we've turned a corner or not, but this is definitely progress. Baby steps. We'll keep taking them until we're diaper-free!
On another positive pee-related note: We're using cloth diapers at night now rather than disposable. That way we can make up for some of the waste of using disposable diapers at daycare. Hurrah for green parenting!
