How big of a deal is it to pick a title that is already used by a few other books? These other books are not wildly popular. I am writing a book about digital addiction and how to help your child. The title I might use is Left to Their Own Devices: Six evidence-based approaches to help your screen-addicted child. The other books have different subtitles from mine. If that is a really bad idea, what about this title Screen Time Rescue: Understanding Your Child's Digital Addiction and How to Help Their Brain.
