My son is just over two and is going through periods of time when he won't sleep either or he won't go down at his bed time. I have started putting him down at 11am every day and I let him cry a little--most of the time he goes right to sleep, other times he just cries. At that point, I let him get up and I make sure I put him down early for bed. He finally has gone back into taking regular naps. But occasionally we hit no nap weeks. I would agree that it's good to atleast make them sit quietly and read or something for an hour if they won't nap. On no nap days, that's my only sanity.
