It all depends on how you want to go about inserting the new node.

What you'll probably want is the InsertBefore and InsertAfter methods.  Below is the sample code from the InsertBefore method in the VB.NET help files.  This'll insert the new node (elem) as the first node in root's ChildNodes.

If you wanted to insert it as the second node, you could use either
    root.InsertAfter(elem, root.FirstNode)  ' As long as there is a FirstNode
or
   root.InsertBefore(elem, root.ChildNodes(1)  ' As long as ChildNodes.Count >=2, so that there is a ChildNodes(1)

Hope this helps.

Sample code:-
Option Strict
Option Explicit

Imports System
Imports System.IO
Imports System.Xml

Public Class Sample
   
    Public Shared Sub Main()
       
        Dim doc As New XmlDocument()
        doc.LoadXml("<book genre='novel' ISBN='1-861001-57-5'>" & _
                    "<title>Pride And Prejudice</title>" & _
                    "</book>")
       
        Dim root As XmlNode = doc.DocumentElement
       
        'Create a new node.
        Dim elem As XmlElement = doc.CreateElement("price")
        elem.InnerText = "19.95"
       
        'Add the node to the document.
        root.InsertBefore(elem, root.FirstChild)
       
        Console.WriteLine("Display the modified XML...")
        doc.Save(Console.Out)
    End Sub 'Main
End Class 'Sample
