crab walk

I set Preston up with some toys on the floor about five feet away from myself in front of the tv. so i start my workout video i am getting into it, i step into a round kick and am dropping out of it when i notice a little face looking up at me right where my foot is about to land, oh no i readjust the landing position of my foot and throw my self off balance no thank goodness i did not step on my baby.
so i put him back on his mat and go back to my workout video and not 2 min later the same thing so i pick preston up and do some of my workout holding him (i must say kickboxing is hard with a giant 6 month old in your arms, hard to bablance) so i decide this isnt working and i place him back on his mat, all these interupptions i ahve lost the rythm and haven't really gotten back into the video, so i look behind me to check the location of Preston, and i see him on his back, propelling himself forward with his feet, and pulling on the couch with his arms ok so to say the least this looked hysterical, so i gave up trying to work out and tried to get a picture/video of him doing this move....unfortunately he sees a camera and won't move.....maybe someday....
