Paris and Carlie Jean learned how to get themselves under the covers a long time ago. They go back in the sleeper and burrow in and sleep. Ella, still the baby, hasn't figured it out yet, so she just sleeps on top of the covers and shivers, unless I go help her get under them.
I went back in the sleeper yesterday to get something and sat down next to Ella. She was so groggy from sleep. Of course Carlie Jean had to poke her head out and see if there was anything going on worth leaving her cozy nest. There wasn't apparently, because she never showed more than her head. That's kind of unusual for her. She is usually the first to come bounding out from beneath the covers. She must have been really enjoying her nap and the warmth.
