Retrieve All Parents From The Database?

I am using MVC3 and EF 4.1 (Oracle DB). Let's suppose I have:

Public Class Parent
Public Property Id As Integer
Public Property Name As String

[code]....

I want to retrieve all parents from the database and for each parent I can access its children.I want to do the following:

Dim firstParent = (From q In db.Parents Select q).First()
For Each child In firstParent.Children
'Do something
Next

The problem is that I would like to enumerate the children from the youngest to the oldest. Is it possible without the client-side sorting? If yes then how can I achieve that? I know how I could achieve what I want with an SQL query, but I cannot make it work with LINQ...

EDIT:Since this seems not to have a solution in my case and sorting everytime I request data is not an option, maybe there is something I can do when I insert the data to the database? I do not have a control on which order EF saves items to the database when I call db.Save(), but maybe there is some syntax I could use to require ordering based on some property.
