I solved the exact same issue ( I don’t know if it is correct or not ) by redirecting the parent page back to the blog url. For example, if the parent page was Tutorial Videos, and there were six child pages under it, clicking the parent page just re directed to the homepage.
There is a couple ways you can try to accomplish this. One is custom fields – here is a straight forward instruction for that:

This may actually prove more practical in the long run, and seems a little more “on point”
Redirect Parent to First Child Plugin
It’s the third one down on the page. If you try it, you might let me know what you think. If it works okay for you, I might give it a try!

Good luck!
