Bath Time

Why do little boys hate to bathe so much? My son has a technique to avoid ever actually taking a bath. He goes to sleep before time to take a bath, but always at a different time. I moved up the time, he started going to sleep earlier. I would watch him like a hawk, he would fall asleep during the few minutes I wasn't watching him. He can actually take off his clothes, climb in bed, and fall asleep in little as two minutes. And if you wake him up, he can't fall back to sleep. I have to change the time every day.
