Family Link is in a beta-tester program right now. It was just launched in the United States. I think it tries to address some of the concerns you have, that in the context of a young child, how does a parent have some level of awareness and control over what the child is doing with online tools? It creates family profiles, including a profile for the child, that the parent can limit. The parent can limit the types of sites they can visit, limit the amount of time the child uses the devices. It can provide a record of what in fact they did visit and what they looked at so there can be that honest conversation among family members around how they're using devices and what they're seeing.
