The "anti napper"

 Now that you have discovered that you can sit up and play in your crib nap time has been quite interesting. First you decide to sit and clap your hands.

 Now that you know I'm watching its time to ham it up for the camera

 Thinking about pulling up.

 "Mommy can't see me if I turn my back to her"

 The moment your realize I can still see you.

 Attempt number 2 to pull up

 Almost up

 Still going strong

I laid you back down and turned on your light show. It got very quiet so I assumed you finally gave up and went to sleep. This is what I found when I went back to check on you. Oh boy!
