Nest

On one of our first days of Christmas vacation, Adam disappeared into the basement for some time.  A while later he came upstairs and told me he had something he wanted to show me.  I followed him, and found that he had gathered pillows, blankets, costumes, basically anything that might be considered soft and comfortable.  He took all those things a constructed a nest.    It was very impressive, it was several inches high, and balanced to make it even on top--yet so the sides would not fall in. 

Later that day he was downstairs with Mike and Austin.  He apparently became bored, because he crawled in his nest and fell asleep!

Looks like a cozy nest to me!
