@Nellyelora Yes, I'm in London and have always lived here (except for when I was a student) so I've never needed to drive.
I actively dislike being in cars and my kids tend to throw up if they spend more than half an hour in a car, so they have been using public transport all their lives.
Buses here cost £1.50 if we need one, tube is a bit more, and I am absolutely sure that it works out cheaper than running a car.
I wouldn't live somewhere that I couldn't access shops, park, etc. within reasonable walking distance.
I didn't have an option with ditching the buggy, with my first child I was heavily pregnant and couldn't push it any more, with my second he was really heavy (over 15 kg) and knackered two Maclarens before I gave up on it!
They also both dropped naps around the same age (two and a half).
They probably walk 2-3 miles a day on a normal day at home, and easily cover 10+ miles a day when we're on holiday and we'll jump on a bus or in a cab if they get totally exhausted (not often).
