I've added screen time restrictions to the ipad my kids use (5 and 7, but mostly the 7 year old - the younger one seems to not care much for TV of his own volition). I set it to 10 minutes per day per year of age (so 1h10m per day, as only the 7 year old seems prone to overuse). This is a maximum, but he reaches it most days and then after some grumbling accepts it and does something else. One advantage: when the iPad "decides" it's time out instead of me or my wife, he is somehow a lot more ready to accept it! With both our kids we only started allowing them to watch TV/use screens at around 2 years of age using roughly the above formula.
