With a simplified interface, the new feature enables parents to adjust the timings at any time.
Parents provided feedback to Facebook regarding Messenger Kids that controls to make the app inaccessible during times like dinner or bedtime.
As far as what happens when sleep mode is activated, the app won't deliver notifications, kids won't be able to send or receive messages, and they won't be able to access the app's camera functionality, either.
With Sleep Mode, parents can set a designated off time and each day at the designated time, the app will "go to sleep" and not be accessible to kids during those hours. Parents can control sleep mode from the Parent Control centre through their own regular Facebook accounts.
According to YouTube, "Parents know better than anyone what they want their children to watch". For example, you could prevent your kids from using the app after 8pm on weekdays when they should be sleeping or doing their homework. Still, some parents found disturbing videos were making it into the app and were viewable because they were not caught by the human curators. If they try to use the app, they'll see a message telling them that the app is in Sleep Mode and that they should come back later. To that end, Facebook has opted to roll out a "Sleep Mode" feature for the app which will give parents more control over how and when their kids can use it. However, growing concerns over the impact that digital devices and social media have on children's emotional and cognitive development has led to calls for Facebook to ditch the app.
YouTube Kids was introduced in 2015 for children of preschool age and older, and it says it has more than 11 million weekly viewers. In addition to sleep mode, parents can add and remove contacts, delete the child's account, or create a new account right from the control panel. Messenger Kids application is absolutely for free and you can download the app for both, iOS and Android platform for free.
