Child Links Content Type?

hi all,

Just a quick question - is there anything I can use in terms of content type, to make the body of the content display a list of that page's child links?

ie.

Category 1
-Sub-Category 1.1
-Sub-Category 1.2
--Sub-Sub-Category 1.2.1
--Sub-Sub-Category 1.2.2
--Sub-Sub-Category 1.2.3

The Basic Page which I have used to create the Sub-Category 1.2 level should display:

Sub-Sub-Category 1.2.1
Sub-Sub-Category 1.2.2
Sub-Sub-Category 1.2.3
