Play on Pillows

Nathan keeps all the extra pillows in the house on his bed. He used to need them to keep him from rolling out of bed, but now he just likes being surrounded by pillows while he sleeps. He also likes playing and jumping around in the pillows. We bury him under a huge pile of pillows, we stick our hands under the pile, and tickle him. Then he thrashes all around, and breaks out of the pillows.
Kathryn gets mad if she's not part of all the fun. She likes playing on the pillows now, too.
When Nathan breaks out of the pillows, she laughs hysterically.
Sometimes she goes looking for him under the pillows, too.
With those hefty legs, she's going to be able to climb on those pillows all by herself pretty soon.
