I am fairly new to Adobe and trying to figure out how to create a custom metric that would show the following:
Average page depth of first childrens product viewed.
I already have all my children's products in a category called 'Childrens' so the categorisation part is not a problem.
Any help would be greatly appreciated.

I am not sure if you already have pathing enabled in your implementation. If it is working you can look into some pathing reports for the information especially the full paths report and select the desired page as the entry page.
Let me know if that works.
