I think that a lot of family relationships can become very strained at the time of assessment and diagnosis. I also think that those feelings of the doubting dads (mums?) and reluctant relatives have value.
I believe that the feelings may be more worthy of a hearing than the phrase "in denial" implies and it might help to learn more about them.
I wonder whether the quasi-medical terminology by professionals used can put barriers between the different people who love the child at the time they most need to work as a team.
It would be nice if anyone described in the thread title felt able to speak here.
