Thanks wbmnfktr.
I have had partial success by tweaking my original code as so ...
<?php
foreach($page->child->repeater_1 as $field) {
echo "{$field->repeater_heading}";
echo "{$field->repeater_body_content}";
}?>
However, this only works for the first child page, so not ideal.
I will take a closer look at your suggested code now, thanks again.
