Eight kids - two young sitters!
It’s hard to imagine many people now putting as much trust into kids aged 11-13 to babysit as the parents did in the books. I’m rereading some of the books and am currently reading #23 - “Dawn on the Coast.” Two sitters are sitting for eight kids in one chapter, and two of the kids are babies. Six of the kids are under age six, and the oldest seems to have some issues with rudeness and things like that. I have been babysitting for a long time and have noticed that many people now prefer adult sitters, especially with babies.
