Personally I remember that I was not allowed to watch Television as often as I wished. Thats why I was very excited for Christmas holidays because during this time we watched a lot of Christmas movies together. Usually I was allowed to watch TV before going to bed but maximum for one hour. Also I remember was fully against an own TV in my room. With years I recognize that it is the right decision. I really dislike it when I see toddlers and young children in restaurants being occupied with watching something on the tablet.
In order to prevent children from having attention problems it is recommended stimulate the child with cognitive stimulations, such as reading, singing, going to the museum etc. In fact, each hour of cognitive stimulation reduces the chances of attention problems by about 30%.
