Please, please, please tell me it's not so.
Yesterday, I ran with my running group and when I got home it was during their morning nap time. Hubby said that they had been chattering for over an hour and he had tried several times to get them to go to sleep. We finally went ahead and got them up, so we didn't mess up any other naps or sleeping for the rest of the day. In the afternoon, we put them down at 1PM (their normal nap time), and they slept for almost 3.5 hours! WOW! They normally will sleep for about 2, but I assume they were trying to make up for the hour or so that they didn't get that morning.
Today, they went down great for their morning nap and slept for about 1.5 hours. Today, they went down around 1:30 and it was uggggly. Lots of crying. Lots of listening to the monitor and trying to wait it out to see if they'd fall asleep. Two doses of Tylenol because there was a lot of hand gnawing, but no sleep.
When I got them out of their cribs for a snack, they happily ate and drank. Now they are playing and life seems good.
I thought they would transition to one nap around 18 months. Is this just a fluke?
