Thanks, rockzmom! It's much clearer now. I thought that calling a baby anything but "it" was wrong for some reason.
It is interesting that you mention this "it" thing as when we were looking at high schools we attended several open houses. At one of them an Assistant Principal was speaking and retelling a story and could not recall the student's gender, so she referred to the student as an "it." I was shocked and appalled that an administrator who was trying to impress parents and students would say that! She also said "ummm" maybe 400 times. Needless to say, we quickly crossed that high school off our list.
