I remember pictures of myself as a baby in a contraption similar to this. We call it the 'JOLLY JUMPER' In my pictures, I must say, I did appear Jolly. Alone, attempting to jump in a jolly manner with no one there to break my stride. Poor Walker, not so sure how Jolly he could be being bounced up and down sporatically. I'm pretty sure this thing is meant for the growth and development of the baby's large motor skills, not for the baby's sisters to torture him. Oh, and did I mention the DrAmA??? Oh the pure drama of who gets to push Walker and how it should be done! It seems as though everything they do when it comes to Walker becomes heated. Judge for yourself. I'm not just saying this because they are vicious on this video, but honestly, Ava and Regan are such good little friends, but I swear caring for Walkie Talkie brings out the worst in both. I swear, If Walker lives to see his 1st birthday, he will be able to weather any storm that life may throw at him...trust me!
