Here are some of Kaitlyn's favorite things to do lately.

Opening drawers. The ones in her room are easy to open and close, so she enjoys playing with them and trying to empty out the contents. If she's really motivated, she'll get up on her knees so that she can reach more things...until she tries to close the drawer with her fingers still inside. The tears are usually not far behind. Mean drawers!
Emptying the toy basket. She's not satisfied until she takes a perfectly contained basket of toys and removes each toy one by one.
Pulling up on the window. She tries really hard to push herself up to a standing position using the window sill. She also enjoys just looking outside.
Playing in the laundry basket. Obviously she has to have some help getting inside, but once she's there, she has great fun playing peek-a-boo and pulling up on the sides.
