Three-year-old knows what time it is

Back when my son was three, he had been waking up really early, which was keeping him from getting a good night's sleep. He's extremely bright, and already knew his numbers, so one day, my wife and I decided to put a digital clock in his room so he would know when he should go back to sleep and when it was okay to get up.

That night, at approximately 8:22, as we were putting him to bed, we explained the rules: "When you see the seven on the clock, it's morning, and you can get up!"

Five minutes later, he comes walking out of his room. "I saw a seven! I get up now!"

The grin on his face made it clear he knew exactly what he was doing. The only fallout was a laugh and a hug, before he went back to bed again.
