My oldest use to get up in the middle of the night all the time when he was about that age. He use to sit up calmly in bed and hum that frikin Barney theme song over and over and over. I didn't have any Barney taps at my apartment, but my ex had them all. I think he missed them when he came over to my place.
Anyway, you sound well.
