Here's a photo of my twin nieces, now 6 months old, in their natural habitat. One can sit up by herself, the other can roll around. I'm sure they'll be crawling soon.
I just spent 10 days at my parents' house in Ohio sorting through boxes and boxes of paper, carefully wrapping fragile knick-knacks, and trying to figure out how they will ever fit 3,000 square feet of stuff into a 1200 square foot house in San Diego. They are moving to SD permanently in February.
It was quite strange seeing the old house stripped down to bare furnishings-- knick-knack-less and paperless, as it were.
