Kids need a large house? Not places to play outside with their friends? What is a kid going to do in the suburbs that doesn't rely on being ferried around in a car for hours each day?
Urban living doesn't often give much space for kids.
Also have you ever been in a suburb? They usually have parks and playgrounds everywhere. Especially at the school that the kids attend, which is likely easy to walk or bike to for the kid.
Some suburbs have community centers.
Some suburbs in Calgary have private lakes with parks and playgrounds that kids can go to whenever they want. They can go skating on the frozen lake in winter, swimming in summer, in walking distance to home and without their parents.
Also in the suburbs houses have yards, which are even better than parks and playgrounds in some ways. My friends and I dug up a huge trench network in his parents yard one year. His parents were chill about it, we were allowed to go out with shovels and pickaxes and dig as much as we wanted really. Why not? They weren't using the yard for anything else and we had fun with it
Or they can hop on the bike trails and head to the library or recreation center or the gymnastics center.
If they're old enough there's also bus lines right outside my door that connect them to the largest light rail deployment in the hemisphere.
There's also all the space for indoor activities if they'd like, they don't need to go anywhere to partake in a lot of different activities at home. Because, we've got space for crafts and a garage and yard.
