Goof in Goofs?

About the baby mix-up, I was watching that part just now and it's not a mistake. Karsh tells Illeana to take Apolla and says he'll take Artemis. He says this AFTER he has picked up Apolla, while switching her with Artemia, who Illeana picked up. They both then leave with the appropriate baby, so that's not actually a goof at all.
