This may be of some interest.
YouTube reportedly considered screening every video for kids 8 and under, but it backed off at the last minute.
One of the reasons I seldom let my young kids watch YouTube unsupervised is because I don’t trust its recommendation algorithms. Even when YouTube’s suggestions don’t completely run off the rails into unsafe territory, they can easily be overrun by toy unboxing videos and other assorted junk.
Thank you for reading.
