My 17mo ds naps one time a day, usually around 10-11am. He will sleep between 30 minutes and 1 1/2 hours (very rarely, 2 hours).
I've discovered that if I let him sleep (even half an hour) when he seems tired around 3:00, we're up until 10 or 11pm. If I don't, he goes to sleep around 7:00 and stays asleep (with one or two night nursings) until 5:30-6:30.
When he does go to sleep very late, he still gets up at 5:30-6:30 (maybe he'll "sleep in" to 7:00!).
Am I doing harm to him physically by keeping him awake in the late afternoon?
He's never been much of a napper. Cat naps, 15 minutes here and there when he was younger. The longer napttimes started after he was a year old.
He just seems to get more sleep time when I make him wait, but I'm feeling guilty...
