Jason at bedtime

This is what Jason has been doing lately at nap and bed time. He's driving me nuts. I'm not very good at letting him just cry. He's a stubborn little cuss and will cry for a good hour or two before he collapses in exhaustion. By then it's 3:30 pm or 4:00 pm and then he's sleeping until 5:30 pm or 6:00 pm. What to do, what to do?

Notice the smirk that he gets on his face. He's a monkey!!!!!!
