Where have all the naps gone?

Take a look at this picture cause it's something that rarely happens around here anymore. My lovely SLEEPING child has decided that naps are a thing of the past. He is TOO busy doing things that he doesn't want to fall asleep for anything! For about the past year, he's been doing 1 long nap in the afternoons. Usually around 2-3pm and he would sleep for 3-4 hours. Now, he is finally tired enough to go to sleep around 5pm (calculate this and you'll figure out what time we get to bed at night) and sleeps for about 2 hours or so, waking up irritable and cranky. You'll see that he has to sleep, day or night, with his cars. hehehe He takes them to bed with him, one in each hand, big or small...funny guy. Time check: 5:43pm. Better late than never?
