None of this is rocket science to anyone born before smart phones, had kids before the phone based childhood ( my kids born 99/02 are on the edge) and/or work in education. Girls and boyse are hit differently ( I only have boys) and at different ages. We need to return to a play based childhood at home and at school. Phones have no place at school and using them to entertain your child while you shop, drive, eat is a disaster
