The doctors and nurses made a huge deal about how alert my boys were at delivery. I just assumed it was because they both have really big eyes! LOL! They did have great head control and good eye tracking very early. Even as very young infants, they always seemed interested and curious, never wanting to miss the action.
Our eldest nearly "frog jumped" off of the table at 9 days old when we were getting newborn photos done. I remember the photographer making a big deal out of that too. (Of course, this was the only time he's ever been ahead of the curve for gross motor skills)
Looking back, I guess I didn't realize these things would be the first (and nowhere near the last) times of people noticing, commenting, etc. about how different they are. Eldest DS had a day recently when everyone seemed to notice him. (Wow, he can read? How long has he been reading? Ohh, Ohh, read this! Wow, he can multiply? . . .) I told DH that DS is a "circus freak" -where everyone points and stares! Sometimes, I think "normal" sounds so perfectly inconspicuous!
