some things could have been done differently but it is hard to predict and prevent suicide/infanticide due to MH. signs may be there but SS cant go in and remove children on a hunch.

"Tania Clarence, a woman who had suffered depressive episodes throughout her life and had a family history of suicide"...
but if the family were rejecting help or unable to express the darkest thoughts how could people really help? you cant predict..she waited till husband etc were not there to do this. there is no indication she told the husband (or any professional) what she had in mind.
it is draining hard etc. (I ahve ds with severe LD/ASD - was v challenging few years ago) but it's the mental health of the parent which may or may not be diagnosed/being treated that kills - unpredictably.
my exp was being treated for depression, had expressed his difficulties with our ds (SLD/ASD etc) but I had no idea he was going to attack DS until he did so - he picked him up by his neck and threw him across the room, fortunately ds was ok. n
one of the psychiatrists psychologists who had assessed exp had said to me oh you better watch out he might attack ds... you cannot leap from "depressed mother" to "mother will kill".
you cannot leap from parent of child with disabilities = possibility of murder.
nor do we want every parent with depression to be on murder watch... whatever the disabilities of their dc. that's not realistic or desirable is it?. how do you grade the possibility? level of disability? level of past depression?
I can see how even with depression/ expressions of being unable to cope etcetc you just cannot predict how that will pan out in a moment.
even with the best engagement with professionals (and here it seems to have been difficult on both sides, including some failings on professional side) unless someone says "i plan to kill my children today" then how will you know?
the judge with all the evidence decided she was mentally unwell. you can do everything but sometimes you just cant predict or prevent.
