My children never cease to amaze me.
A while ago we decided to move the trashcan out of N's room (and to keep it in the hall instead) to make it easier when it was time to take the trash out each week. This way we didn't have to worry about emptying the trashcan before N went to sleep.
Anyway, the other night I changed N's wet diaper, balled it up, and tossed it toward his bedroom door so I could take it out to the trashcan after I put him to sleep. I ended up putting him down on the floor for a minute during the bedtime routine. He immediately crawled over to his dirty diaper, picked it up, crawled out to the trashcan in the hallway, stood up and put the diaper in the trashcan. I don't know if this was planned out or just a fluke, but I sat there dumbfounded and then yelled to B, "Did you see that? N just threw away his own dirty diaper!"
Two days later I'm still amazed.
