Just googled it and in principle it sounds like the parenting methods most of us will have used for donkey's years, caring for our children, noticing their individual needs and traits of personality and supporting them.
However, it does sound very cold and clinical, talking to children as if they were an adult - yet researchers say babies learn language by the bibble babble of baby language and nothing, that I could see about cuddles and love and interaction between parent and child, the parent seems to be the child's servant and not allowed any personality of their own.
As I understand it, if your very young child chooses only to eat icecream and wants to walk to the shop naked from the waist down, you respect their views and choices and let them do it.
I think it is a money spinner for the author of this new fad way of parenting, almost every site had her name on it.
