Everyday Peter is learning new things and becoming more and more mobile.
Just when I think it is alright to leave him in the living room for his alone play time, he learns to turn on the TV.
When I think my desk is "baby proofed" with the doors closed (it is an armor), he learns to open the doors and "goes through" all my files.
And when I think he cannot climb onto the couch, he figures it out just so he can knock over all the stockings hanging on the railing... then manages to wedge himself between the couch and the side table.
It never ceases to amaze me how much trouble one 16 month old can get into when mommy turns her back!
