High density doesn't mean only building housing. You can build housing around a large park that gives children a safe place to play and explore. Shops within walking distance allow them to experience some responsibility running an errand or to buy themselves a treat with pocket money. At least in my opinion urban living with a sensible balance of retail/nature/housing offers children much more independence than they'd get in the suburbs where they rely entirely on their parents to get anywhere.
