I think emails should be sent or phone calls made to everyone who has a child on them to ensure that they are aware of the new information.
I think mermaids and the tavistock etc should be made to tell every single client that the information they were previously given by them is no longer true and these are additional factors they need to consider.
All this quiet changing of info is actually incredibly sly. Its covering the arses of thise who know full well there are law suots heading their way whilst absolving them responsibility to patients currently on the pathway.
