Personally I find it odd that tv shows and films focus so much on Down's syndrome when it's only one of many genetic conditions that might lead to such a storyline.
It would in my opinion be a good opportunity to educate people about the lesser known conditions.
I understand to a degree why they choose it when there's a character that will need introducing at a later stage in the form of a baby and then a child because it has clear visible and well known features and there are some amazing actors with Down's syndrome which I am sure writers and producers are aware of so there's sort of a reputation and history there.
With other conditions they might be tempted to cast a non disabled actor to play a character with a disability which can be problematic in itself
Politically in pro choice.
Personally I've had 2 mc and the thought of aborting a pregnancy horrifies me, yet is/was a really possibility for me due to my own health - something else which very rarely comes up in tv storylines - conditions that can result in maternal death at childbirth.
Occasionally pre-eclampsia is used but again this is but one condition which can cause this and is generally well understood and recognised.
I have a rare condition which does not present until the 1st labour and birth but which means ANY Future pregnancy is contraindicated as would be potentially fatal.
If I were to become pregnant I would be strongly advised to terminate for the preservation of my own life, though I've actually been told I must do all I can to avoid getting pregnant at all (and yet couldn't/can't get sterilised on nhs!)
Tv shows and especially soaps recycle the same storylines with the same conditions repeatedly.
They don't have a responsibility or obligation to do so but they reach a wide audience and could do immense good in educating and stimulating discussion on lesser known conditions that may well be affecting their viewers.
