Hi. I'm guessing that the days of two naps are coming to an end. My son seemed to adore both of his naps each day until just about the same age -- a little under 2 years. Then, suddenly, he went down to one nap a day -- sometimes in the morning, sometimes in the afternoon. No matter how tired he seemed/acted, he would only sleep once a day. For awhile his schedule was really disrupted. If he went down too late in the afternoon he'd sleep for hours (couldn't wake him up...) then, of course, he'd be up all night! I'd say it worked itself out after a couple of months, and he ended up taking one afternoon nap until about age three. After that, no more naps! But by then he was in preschool, so I still had time to get things done! Best of luck to you and your sweet boy...
