I'm turning to you, Internets, for help.
Here's the deal. Carter has not napped in over a week. Every once in a while he'll sleep for 45 minutes or so, but it's rare. He's obviously tired (whining, rubbing his eyes, laying his head down) but when I put him in his crib, he stands right up and starts screaming. I've tried putting him back down a gazillion times, holding his little butt down so he can't get up (this starts to work but then he pops back up as soon as I remove my hand 10 minutes later...a girl gets tired!), and letting him yell (which just makes him even more angry and eat more of his crib).
If I take him out of his crib, he's fine. Not yelling or screaming, although still obviously tired. If we get in the car, he falls asleep immediately in his carseat.
Nighttime is fine. He goes down without a fuss (please don't let this be a jinx!) and sleeps 11 hours or so. It's just napping.
