N.G.
I remember my oldest daughter being this way, but setting her in a crib with a crib toy that played music was her routine for naptime. She would play with it for a few minutes, fall asleep, and when she woke up, she'd be back to playing with it, kicking it around, etc. Just set him in his crib at naptime, and don't respond to his beck and call. He'll get the point.
