One decision down, one to go

I didn’t mean to keep you waiting this long for an answer. We eventually decided on the Smaller School and ZM called the Big School and told them we wouldn’t be filling her position.
It wasn’t an easy decision, especially because the Big School had been in our plans for such a long time, but in the end I think we are both more comfortable with the Smaller School. I just never imagined we would be in the situation where we could actually choose. It’s hard enough to be accepted in either of these schools, let alone in both.

Now we have another decision to make, which is about transportation. As you remember, Big School was at walking distance from our house, so we never really gave this issue much thought. Now we have to.
In the morning either ZM or I will drop the kids off at school, so no problem there. But in the afternoon none of us will be able to pick them up. We basically have two alternatives: either our nanny picks them up or we can hire a child-transportation service, which is really expensive. So we have decided to explore the idea of the nanny picking them up. But this leaves us with another problem: How?

Our nanny doesn’t drive, so there are two ways she can pick up the kids. She will take the bus to the school (practically door to door bus, and about 15 minute ride) and then they will either take the bus back or take a cab. ZM is all in favour of them taking the bus home, and maybe taking a cab if it’s raining (which happens about twice a year) but I’m not so sure about it. What do you think?
