When the Gospel reading refers to a child as an "it"...

From today's Gospel (Mark 9:30-37) according to the NAB:

Taking a child, he placed it in their midst,
and putting his arms around it, he said to them,
“Whoever receives one child such as this in my name, receives me;
and whoever receives me,
receives not me but the One who sent me.”

Now, according to the RSV:

And He took a child, and put him in the midst of them; and taking him in His arms, He said to them: "Whoever receives one such child in My name receives Me; and whoever receives Me, receives not Me but Him who sent Me."

This "it" thing has bugged me since I first heard it. Certainly we don't know whether the Lord took a girl or boy into his arms, but in the cause for political correctness, I'd much rather have the child assigned some gender...some humanness for Heaven's sake. Call "it" "her" if that makes everybody feel better—but "it" isn't really acceptable...is it?
