One of my daughter's very favorite things to do is to get under a sheet, blanket, towel, shirt, (whatever she can find basically) and just sit there. Sometimes, she'll walk around with it on her head, but for the most part, she just likes to sit under the blanket and do...well...whatever she does under there?! She just sits...for a long time sometimes. I just wonder what she's thinking or doing? Sometimes if the blanket or sheet has pictures on it, she'll point to them and say the names of the pics out loud. But for the most part, yeah, she just sits there really still and quiet. Weird and quirky, huh?
