Well I have to say I don't feel as worried knowing that other los do the same thing.
Tonight was odd, he wanted to sleep sitting up

. Yep, my little Graydon kept sitting up in bed to do what I call his mantra hum (which puts him to sleep). I went in a few times to make him lay flat and his hum just got louder as he was irritated about being made to lay down! Finally just let him sit up, thinking he'd lay down when tired but nope, he leaned far forward to put his head down on his knees to sleep

. Dh went in and rolled him over, which woke him and got him fussing. So dh then sat him up again and he immediately put his head to his knees and fell asleep again, all happy. We did wait until he was in a heavy sleep and laid him down again.
