Our little guy is starting to get a little mobile. When we put him on the floor for tummy time, he's beginning to pick himself up onto all fours, as well as inch forward, grunt by grunt. It's quite remarkable to watch him go.
But I guess I shouldn't be surprised. Jada was very weak in the legs when we first got her, on account of being malnourished and in a crib for most of her first seven months, but she caught up real quick and was soon crawling and walking and climbing like the next kid.
Aaron, on the other hand, got some physical stimulation and plenty of food in his first months. And that good start is really showing now. Go, little guy!
