I agree with Deb. Make sure he has used up his energy. Boys especially need to be more physical. I can sympathize with you about the nap thing. My son took naps up until he was in Kindergarten, but my daughter, now 3, quit as soon as her big brother started school (just this year). If I am out running errands though, she will most likely fall asleep in the car. I am still a car napper, so maybe that just runs in the family. Back to what I was saying...I remember when my son was about 3 or 4, I used to take him out into the backyard and play race games with him. I would count how fast it took him to run from one fence to the other. He loved to see if he could beat his previous time, and it wore him out enough to get to sleep easy at night. My kids don't drink any soda, but I know some parents allow that for their children, so I will just add, if your kid does drink sodas with caffine, limit him and make sure he doesn't have any at least 5 hours before bedtime. Hang in there, you will figure out how to get a handle on it.
