A Cry for Help!

OK world, or to anyone who actually stills looks at this much neglected blog...I am desperate and need any worthwhile advice. MHS decided that at 20 months old he is too old for a nap and mommy is losing her mind! For the past week and a half I have fought him for upwards of an hour to get him to sleep and the only time it worked, he slept for 20 min. He can climb out of his pack-n-play and the crib and I just don't know what to do! If anyone has experienced this before and has some sort of input to save what little sanity I have left, it would be more than Greatly Appreciated!! I have done the drive in the car thing and that works for 30 min. or so, but I'm wasting gas and he isn't getting great sleep. He has passed the point of tired and is a terror when he is awake because of it. Please, Please, Please HELP!!! Here is a pic. of the little stinker and his angel sister too! Thank heavens for little girls that are nice to their mommies! TIA!
