> Play groups explicitly ban phones because otherwise some parents are always on their phones. This was not possible before smart phones. Yes, it was. The parent could be chatting to other parents and ignoring their child, the parent could be reading a book or magazine and ignoring their child. The phone has just made it less explicitly signalled. If you want to read a book at a place you have to bring it to that place, you have to consciously select out a book and carry it with you; whereas your phone is light and you carry it everywhere, so it is easier to slip into that behaviour.
