I hadn't heard this story so my only knowledge is the two links posted
I am shocked but as Matt says, I doubt it's an isolated case.
I was happy playing out with my friends, going swimming training and being taught the history of London from the top deck of a routemaster bus by my fantastic Grandfather at that age.
Note the pattern in that statement, all those activites involved the care, involement and guidance of my close family members. I loved music and was allowed to attend concerts during school holidays, I was treated quite fairly at that age (later it changed) and I responded by respecting my parents wishes. I would NEVER have got up to what they did.
Goodness knows how these children have been brought up. Just think, it's quite possible for this baby's grandparents to be no older than thirty
When DH and I bought eldest DD home from the hospital that first night, we looked at each other and were petrified of being left alone with this little baby, I was 31 he was 35 for goodness sake! Imagine how these children feel about having a baby to care for.
