People would work it out...

In Sydney, we have always had daycare next to home or work, in San Francisco I put the kids in a bike trailer.

The number one thing that worries me about my 9 and 12 year old getting to and from school are the cars. The 12 year old could bike to school if it were not for cars. The 9 year old walks, as did the 12 year old before starting high school and catching the bus.

Cars can be handy for carrying stuff. On the other hand I like strollers as a shopping trolly that goes all the way home.

In my family the person who does not work does not drive at all...

And disposable diapers (nappies) are cheap delivered. And you can use re-usable ones with a service that comes to your house.
