I've decided that must be it. Because suddenly, I'm noticing, I can't see my feet as well as I could before. And I spilled something on the floor, bent down to clean it up, and gosh, the floor was further away than it used to be.
(The fact that I can no longer look down and see what color underwear I'm wearing, well, that's a personal problem.)
Or perhaps my nearly 42-inch belly has something to do with it. Just maybe. This week has marked the beginning of the "uncomfortable" stage. It's not too bad at all yet, but I can tell where it's heading. (Wait... not to say that morning sickness was a "comfortable" stage...)
The babe has a distinct preference for kicking my right side. He's particularly active in the evening, and usually snoozes while I'm working.
