What’s a tag index?

The Kidtogeny Catalog is a collection of digital pages, with one page for each milestone.  Because there are dozens of pages in the Catalog, it can be hard to find a particular milestone.  The Tag Index can help.

If you know how to use the index at the back of book, you know how to use a tag index.  Why?  Because a tag index is a digital version of a book’s index.

tag is equivalent to an index entry, usually a word or phrase.

The tag index is an alphabetical listing of the all the tags that are found on any page of the Catalog.


Like an entry in a book index, a tag can point to one or many pages.  At the same time, a page can be the destination for one or many tags.

For example in the textbook index excerpt below, the entry (tag) numerosity points to a single page, 275.  On the other hand, nutrition points to 6 destinations.  A particular destination, 275, is the target of two tags, numerosity and object permanence.

How to use the tag index

I’ve tagged each milestone in the Catalog.  For example, you can watch for some milestones when your baby is in a sitting posture.  The sit label tags these pages.

Catalog tags are organized in an alphabetic list shown below.  Click on one, and you will be taken to a list of all sit milestone pages.  Simple, eh?

Note that you can only see individual Catalog pages if you have a Catalog Basic or Catalog Plus membership.
