Unless I'm missing something, it's just:

session.QueryOver<Parent>()
   .Where(p => p.ParentName == "Jim")
   .JoinQueryOver(p => p.Children)
       .Where(c => c.ChildName == "Joey")
       .List();

Subject: [nhusers] Queryover with criteria for parent and child

The following DetachedCriteria will select a list of Parent objects
for each parent that contains a particular child.
So for example this would select a list of all parents named Jim who
had a child named Joey.  I want to write the same query using the
QueryOver syntax and am having no luck.  How would I write this using
QueryOver?

           List<Parent> parentsNamedJimWithAChildNamedJoey =
session.List<Parent>(DetachedCriteria.For<Parent>()
               .Add(Expression.Eq("ParentName", "Jim"))
               .CreateCriteria("Children")
               .Add(Expression.Eq("ChildName", "Joey")));
