Retailers like dm might have general advice on child safety or specific products designed to enhance it. Their websites or customer service might offer guidance.
If you could provide more context or clarify your question, I could offer a more targeted response.
Set daily time limits, bedtimes, and scheduled device locks. Different rules for school days vs. weekends.

Keep an eye on the dm "Mama" or family magazine available for free in-store; it often features coupons or tips on new safety products!
