DS used to be on a pretty regular schedule of napping 1.5-2+ hours in the a.m., and then 1-1.5 hours in the late afternoon. In the past week or so, he has been going down later in the a.m. and sleeping 3+ hours. This is his only nap of the day. It's not really a problem except that he has a hard time staying up till bedtime (7 p.m.), but won't take a short late afternoon nap to hold him over. I don't really want to put him to bed any earlier than that.
Isn't 9M kind of soon to be down to 1 nap?
