These last 2 weeks have seen Alexander progressing so rapidly through his developmental stages. Crawling on the floor, around corners, and over any obstacle - pillows, blankets, chairs, sofas - in his way. Now today, he's pulling up for the first time. He grabbed the edge of the playpen bassinet and puuuuuulllled himself up to standing. Thankfully it was slowly enough so that I could run to grab him before he pitched over the side. Whew, much herding ahead I think.
