Linq: Select First Items from the Child List?

I have the following one-to-many relation between two objects.

Parent
   --> IList<Child>

Now, I have a List of Parent objects and I want the First Child of each parent in the list.

What is the best way to do this using Linq?

You can iterate each "Parent" and find the first of it's offspring:

parent.FirstOrDefault(child => parent.Children.First());
