The main problem with technology, and more or less the only one I feel, is eyesight. Because of staring at a computer screen all day, their eyesight could go bad. For 0-2 years, iPads should be prohibited; for 3-5 years, it can be allowed for one hour per day; for 6-18 years it can be allowed for two hours per day. Children need to experience the outdoors–they need to spend time in "green" spaces.
