I have friends with multiple young children and no nannies who do just fine walking their whole brood around the (urban) neighborhood. You can easily carry quite a lot of shopping bags for 2 or 3 kilometers in a wagon if you need to. Or if you like, you can use a car occasionally for shopping trips (or even a taxi), and for a workday commute and the great majority of other trips, stick to walking/transit/bikes. Even if people just ditched their cars for 80% of their trips it would make the city overall much more pleasant.
