these parents are seriously wrong in their attitude toward illness. But other than that I'd be very wary of judging them based on a short appearance on a television show where they are just two (most likely media-unsavvy) people up against a team of people who's job it is to get the best possible story
^^agree with this really.
Aside from the illness / vaccinations stuff they aren't doing anything that awful. Yes, maybe they do like to be different or consider themselves special but that's not a terrible thing in itself.
I agree that children need boundaries, but a gentle approach based on mutual respect is my personal ideal. It's not always achievable at all and I only have one young DD atm. Might be different later, especially if I ever have more DCs. Perhaps I'm really naive!
Lotus birth is a bit icky and IMHO unnecessary, a bit like eating your own placenta! There's nothing "wrong" with it though afaik.
