Or maybe ends would be a better word. We were a little concerned at Christmas because Xavier seemed to have fallen off his growth curve. But we just measured him and he's grown an inch in the last two weeks. Way! Along with the sudden burst of cleverness and the fact that I had to play full out to beat him at Khet over the weekend (and even then I got lucky), I guess he's officially having his growth spurt. I'm the only one who is sad that he's not a little boy, though. He's been feeling left out of the puberty pool, I know. (We had the same problem with potty-training--sharp demarcation between the big boys and the little boys.)
So good for you, Xavier! We're very proud of you!
