Benjamin really gets into his jumper! He just loves it! I thought this one was so cute because he is naked so you get to see his chubby little body. I know he is not so little but you know what I mean. We were watching AFV earlier tonight and they were played a video of twins and they were 8 months old and Jared and I looked at each other and laughed. Benjamin totally had them beat with being able to move on his own and for size at 5 months. We thought the babies were 3-4 months.
