Circadian Rhythm
Some nights DS (22 mos) goes down without a fuss between 9 and 9:30; other nights he is up past 11 PM. I find that if I don't get him to sleep by 9:30 we are in for the long haul, sometimes it has taken over an hour for him to fall asleep in a completely dark quiet bedroom with me lying beside him; we nurse, we sing a few songs, then I say it is time to be quiet and still. If it is taking too long we get up and try again later.
The evening routine is really affected by his naptime, which variest from 11:30 AM at the earliest to past 5 PM! With very few exceptions, we get up each day by 8:30 AM. The way I see it, I have to encourage naps and bedtime based on his circadian rhythm, which has it's low points at 11:30-1 PM, 5-7 PM, and that little 9 PM window. I would be willing to put him down for the night between 5 and 7 PM, but DH does not return home from work until after 7 PM, and they would not see one another during the week.
Today was a 5 PM nap. I tried several times to talk him into lying down earlier in the afternoon, (I needed the nap myself) but he was just not interested. As a result, he stayed up this evening and didn't fall asleep until about midnight. Fortunately, the late bedtime mixed with 8:30 wakeup should significantly increase the odds of the midday naptime. It's almost like he doens't need a nap except every other day.
For a few days last week, we tried No Nap since he was so uninterested in taking one, but it was clear that he was very tired without the daytime rest, so I am giving as much naptime encouragement as possible, mixed with lots of physical activity. We can spend up to two hours at a time playing at the playground.
IMO, I say don't worry about when babies/toddlers 'should' sleep, just listen to their circadian rhythms. If they are nodding off at a certain time of day each day, seize the naptime opportunity. If they like to be awake at night, so be it. (At our house we end up taping any TV shows that we really want to see.) Also, don't bother trying to put the kid to bed unless s/he is showing signs of tiredness; if it takes 2 hours for the child to fall asleep, you might as well be doing something else during that time, playing, reading books, etc. My favorite is when DH or I fall asleep and DS leaves the bedroom and goes to play with his toys. Thank goodness he is not the type to get into things.
