Django / WagtailCMS - get attribute (eg body text) of child page using get_context

I'm trying to access the body text of a child page in my Django / Wagtail CMS blog. I can return the child page title, but I don't know how to use that to get the rest of the child page attributes. The parent is IndexPage, and the child is IndexListSubPage. My model is:

class IndexPage(Page):
    body = RichTextField(blank=True)
    feed_image = models.ForeignKey(
        'wagtailimages.Image',
        null=True,
        blank=True,
        on_delete=models.SET_NULL,
        related_name='+'
    )

    content_panels = Page.content_panels + [
        FieldPanel('body', classname="full"),
        ImageChooserPanel('feed_image'),
    ]

    def get_context(self, request):
        context = super(IndexPage, self).get_context(request)
        context['sub_pages'] = self.get_children()
        return context

class IndexListSubPage(Page):
    body = RichTextField(blank=True)
    feed_image = models.ForeignKey(
        'wagtailimages.Image',
        null=True,
        blank=True,
        on_delete=models.SET_NULL,
        related_name='+'
    )

    content_panels = Page.content_panels + [
        FieldPanel('body', classname="full"),
        ImageChooserPanel('feed_image'),
    ]

I have tried various combinations in my template:

{{ sub_pages }} //returns <QuerySet [<Page: Page title here>]>
{{ sub_pages.body }} //returns nothing

This returns the page title for the child page, but I also want other attributes, like the body text. Any ideas? I have tried the image template settings from here as well - again, I can get the title, but no attributes. The page has both image and body text in the admin interface.

I got it working by changing the model to include .specific(), as suggested by @gasman. The working model is:

class ProjectsPage(Page):
body = RichTextField(blank=True)

content_panels = Page.content_panels + [
    FieldPanel('body', classname="full"),
]

def get_context(self, request):
    context = super(ProjectsPage, self).get_context(request)
    context['sub_pages'] = self.get_children().specific()
    print(context['sub_pages'])
    return context

And in the template:

{% with sub_pages as pages %}
    {% for page in pages %}
         {{ page.title }}
         {{ page.body }}
    {% endfor %}
{% endwith %}

The title and the body of the child page are now being rendered.
