On their last day of school this year, I talked Rosie and Dash into wearing the same outfits that they had worn on their first day so I could take this comparison photo. They didn't protest at all, and amazingly, Rosie still fit in all the clothing, including shoes (although, I noticed afterwards that she had worn holes through the soles).
While they are standing in almost the same spot, I didn't get the exact angle from the original shot. I was pretty careful to scale the after-shot to an accurate relative size, basing the measurement on Dash's shirt from collar to shirt-tails.
They *have* grown quite a bit, haven't they? Cheers to my rising Second and Fourth-graders!
