Does your 3 year old still take a nap?

Mine used to take a nap everyday like clockwork. For the last 4 months or so, he rarely takes a nap. It is such a struggle to get him to lay down for a nap - so much of a struggle I have just given up. He gets adequate sleep at night 10-11 hours so I'm not so much worried he's not getting enough sleep. . .I need him to take a nap so I can have a break! LOL! My 15 month old takes a nap for 2 hours everyday. Anyone out there have any suggestions on how to get my little 3 year to sleep? Or is it a lost cause? Help mommies (and daddies)!!
