Add nodereference field to webform

First off, thank you for this amazing product. After 3 15 hour days of trying to configure CiviCRM for my purposes I scrapped it and went "old school".
Here is what I am attempting to do.

I need parents to be able to register their OWN children for events.

The parents are set up as content profiles, their children as nodes.

I have created a node reference based on a view with the conditions of nodes of type "child" that were authored by the currently logged in user. I got this all figured out today. Now I am stuck on how I can, from the paid event form I created using the Paid Event content type, allow parents to select their children. Can I create a custom webform for that functionality and insert it into paid event content type? I see I can add fields, but what I need to do is add an addition form that will allow parents to select (only) their nodes (or children).

Hopefully this makes sense. I went from not understanding any of this this morning to having a very basic understanding, but it seems to me I just need to be able to add a webform to the page. Is that possible?

Thanks
