I also enjoy watching the nanny shows and benefit from watching. All us parents can use pointers every now and then. I know I certainly don't know everything about parenting.I didn't happen to see the show you were refering to so I can't speak to what happened on the show. While I would agree that those types of machines can be dangerous, I think that with proper supervision older kids can safely ride. There's always an element of danger and that's why you have to take as many precautions as possible, such as not being in a terrain that is beyond the child's ability to deal with. Anyway, it's could to be aware of the dangers.
Looking forward to more nanny episodes!
