I'm going through the getting started guide At this part

Children
In this case, vegetarian is considered a child note of recipes. When looking at the recipes note, the preview view will list vegetarian (and any other recipes.* notes) at the bottom as Children. Children can also be seen and navigated via the tree view.

I've created the

recipes.vegetarian

note and it's showing in the Tree View, but when I go back to the

recipes

note, there is no section with "Children" in the preview and the vegetarian note is not referenced anywhere. I'm assuming that, if I went back to the recipes note, it would have added a section called "Children" with the vegetarian note. Am I off base?
