For months and months, Paul was an adorable little lump. Six weeks ago, he pushed himself up to sitting position and his mobility suddenly revved up. Sitting, standing, cruising, crawling on all fours -- it happened so fast, and yes, in that order. I turned my back on Paul for a minute, and he's in the mudroom playing with shoes (ick!). Another time, I went to brush Joseph's teeth, and came back to find Paul standing up triumphantly at the foot of the stairs. Love his little proud smile.
