That's exactly my point. They are likely to get exposed to the worst of the internet at a significantly younger age than they will have the maturity and experience to handle (and younger than I can have any hope of trying to coach them in), all thanks to parents who give young kids (I'm talking 8 and younger) smartphones to keep them quiet.

My oldest girl is 5. She's already very aware that other kids in her class have access to tablets and phones. How on earth do I responsibly explain to her the dangers? I have enough trouble asking her to get dressed and keep her nappy dry at night.
