<p>By default wordpress menu system, wordpress can only automatically add/remove <strong>top-level page</strong> to/from menus</p>
<ul>
<li>When <strong>publish</strong> top-level page then add it into menus</li>
<li>When <strong>move</strong> top-level page to trash then remove it from menus</li>
<li>When <strong>restore</strong> top-level page then add it into menus</li>
</ul>
<p>this feature has no effect with <strong>subpage</strong> (child page), but <strong>Auto Subpage Menu</strong> can</p>
<ul>
<li>When <strong>publish</strong> subpage (child page) then add it into menus (if its page parent exists in menu)</li>
<li>When <strong>update</strong> subpage (child page) then update menus</li>
<li>When <strong>move</strong> subpage (child page) to trash then remove it from menus</li>
<li>When <strong>restore</strong> subpage (child page) then add it into menus</li>
</ul>

Auto Subpage Menu

The idea is good but the support is not very good. So if you find another plug-in with similar functionality I would advise to try that!

Good idea but bad support
