I'm not a big scheduled person. I mean, I do all right with a routine, but if I don't have a schedule I don't feel bereft.
Little Man is scheduling king. As a family, we all do better when we respect HIS limits and follow the schedule as he dictates. Breakfast three times a day (along with two lunches and a dinner), naps, and bedtime before 7 PM.
I find that I debate forcing him back on schedule with some flexibility. For example, yesterday around 5 he started to wind down and he could have used an extra nap. But I was worried that if he had slept then he wouldn't eat and would end up having to be woken up for dinner. Then he'd be unable to get back to sleep and it would be ugly. So I kept him awake, fed him and put him to bed early early.
It makes life limited in some ways (though we did go see a hockey game, courtesy of a babysitter who wanted to play with the boy but the boy was asleep), but those are limits that are totally ok.
