Last night I noticed that dd7 had been growing again. In fact, I put her next to dd10--who is not a short girl--and realized that they appear to be the exact same height now.
How did I get "twins" 2.5 years apart? I know children grow at different rates, but isn't it a bit extreme for a seven-year-old to be handing clothing "down" to her ten-year-old sister?
Still, the realization that they share so much DNA yet still are quite different in some ways is a valuable one that ties in with our biology studies for the next few weeks. We will be focusing on genetics.
UPDATE: One of the biology topics we studied today was sexual vs. asexual reproduction. Afterward dd10 did her 1/2 page of Bible reading, which coincidentally was the story of Lot's daughters getting their father drunk and using him to impregnate themselves. She couldn't bring herself to narrate a summary of her reading. What a pity Lot couldn't just clone himself after his wife perished.
