I actually see two divergent trends.
One somewhat like Tashy describes, but the other as RumpledElf describes. There's a real tug of war going on. But, I think the result of this is partly good for parents in that there seems to be more public debate and information around than previously, including questioning the obstetric model of care and necessity (indeed, benefit) of many standard interventions. Some will be caught in the middle, however, with fewer options available to them.
