Hey Gordon! Welcome to the NotionApps community! If I understand correctly, a parent-child relationship is how Notion represents Relations. We have started working on the support for Relation columns. With it, you will be able to view/add/update related pages from the parent page. As it’s a big feature, we will hopefully be shipping it by the end of next month.
You can track the progress of the feature on our Roadmap here, https://community.notionapps.com/t/support-for-relation-columns. Do upvote it so that we can keep measuring the community’s interest in Relations.
