I think I may be confused. Do you want your nanny to take the kids to the library and pick out books (that will be of HER choosing, and may not be what you deem appropriate), take your kids to the doctor (which seems odd to me unless you don't really care about their health), buy them clothes (again...HER choosing, not you), setting up play dates with people you don't know? Or....what? I don't understand your question.
You probably just need a nanny to be there in the morning and after school care for a couple of hours until you get home. Around here they just call it "before and after school care".
I nannied for a family for 3 years and had the older children (3rd and 7th grade) after school. It was my job to make sure they got their after school snack, got homework done, and got any practicing that they needed to do done. It wasn't my job to take care of the house, chores, or laundry. That's a housekeeper.

umm....this wasn't said in a nasty tone at all. I am sorry that you read it that way. This was said in a confused tone. Next time I will note my tone before responding. Also, there are TONS of people out there that do before and after care.
