How to get last child object of a parent model by query

Hi,

Let's say there are two related models 

class Parent(models.Model):

    ...

class Child(models.Model):

    parent = models.ForeingKey(Parent)

I need to fetch every last child of specific parent objects by query.

Is there a way to do this instead iterating Parent objects to gather last childs like:

last_childs = list()

for parent in Parent.objects.filter(id__in=[1, 2, 3, 4]):

    last_childs.append(parent.child_set.last())

Kind regards,

Sencer HAMARAT
