Anyone have a cure for growing up?

Every 3 months I take photos and measurments of the children - it started as part of our study of the human body and we have continued it now since October 07. Here is the latest group shot of my babies. Next Month J turns 11, W turns 9 and then 2 months after that the tiniest man in the world turns 7...not so tiny anymore.

J has grown so much and each time we do this she has grown, no spurts, just consistent growing. W is just managing to stay a little ahead of M, everywhere I go people ask if they are twins. It happens so much I feel like just saying yes becasue it is easier than sayin "no, they are two years apart"...then pointing out which one is older.
