How do you insert a child node in a TreeView Control in WPF C#?

I have a TreeView control that I have created in XAML in a WPF program using C#.

After adding a couple nodes at the root level, I have written code that loops through the tree structure like so:

ItemCollection items = treeView1.Items;
foreach (TreeViewItem n in items)
{
...
}

Once I find the place in this loop where I want to include a child node, how do I go about inserting a child?

Each node has its own collection of nodes, just add it to that. Also realize that if you want to walk the entire tree at a later time you will need a recursive solution.
