Teaching children self-reliance

My husband usually puts Jason down for a nap after lunch. Today my husband got distracted teaching Emily some music. When he realized it was getting late, he searched for Jason and found him already in his crib doing a little final playing before falling asleep. I guess Jason became impatient and put himself down for a nap. He's learned how to climb into his crib. How's that for toddler awesomeness? I can't believe this is the same kid I had to use Super Nanny tactics on just a couple months ago to get him to stay in his crib. Pfff! Who needs parents? The kid can dress himself. He can feed himself. He can put himself to bed. Now I'm just waiting for him to potty train himself. Once he's finished with that, I suppose it's time to send him off into the wild.
