Our son (3) likes to watch videos of some of his show characters he likes, and toys for them, etc. He can navigate on an android phone or tablet to choose more videos when the one he is watching is over. Sometimes we let him do this when we are trying to watch another show he is less interested in. Recently though he has ended up on videos that are entirely inappropriate for him just by following other linked videos that pop up when a video is done playing. He somehow got from Cars 2 toys to a compliation of death scenes from the Final Destination movies. Fortunately he had brought the phone to me saying he wanted to watch something else before anything serious started to show, but I would like to find a way to let him view the safe content and restrict the kid-unfriendly stuff. Setting the youtube safety flag to on doesn't really seem to help with this. I did so and was still able to get the same Final Destination video (but the comments were disabled for safety!). Is there a best option for this or am I better off not letting him look at this stuff for safety reasons?
