To clarify...yes, S is walking like crazy. This surprised me, as I had heard that those who are verbal early (which he is) are usually later on the physical milestones, and visa versa. Well, by 6months S said 'mama' and clearly knew what he meant. He has since added 'nurn' 'dada' and 'dah' (dog) to his vocabulary. "Mama" includes asking for food (perhaps confused with 'mmmm' or 'more'?) and "nurn" includes cuddles and comfort as well as actual nursing. But yes, he talks. He also grunts, growls, clicks his tongue, and 'sings' when he's tired.
He hit all his other physical milestones on the later side...rolling over, sitting up, crawling...and then WHAM he decided to walk. I have no idea what got into him...perhaps it's our hard pergo floors--nobody wants to crawl on them, so might as well get up and walk! :-)
