I meant it purely in the sense that if one of them watches the baby while the other goes out and has fun, it can be a bit of a chore for the one left home alone with the sole responsibility for the rambunctious toddler, inasmuch as the one at home can't really do anything BUT look after the baby during that time. They very rarely leave each other in that position, so it's sort of a special favor from one to the other when they do. That said, I can't swear to the fact that I've ever used the word "babysitting" in reference to Gia, so perhaps I was revealing a bit of cultural bias.
