You get that by living near your parents, which has the added advantage that your parents aren't constantly observing you and your relationship and choosing everything from your interior decor to your entertainment... and when you want your grandparents to look after the kids so you can have some peace, the kids actually go to a different building! And it turns out the fun, community-oriented bit of your friends' kids is meeting them at events or when you invite the family round and being impressed by how much more confident they've got since last time you saw them, not being woken up in the middle of the night by them.
