That's a really extreme accusation
I'm not here to criticise anyone as this is a gossip website so I'm just as bad but I might have to check out of this thread. I'm finding it very triggering as someone who has lots of contact with SEN services.
Maybe K made some mistakes. If 10% of what is being said here is true then she is going to have some really painful regrets. From what I can tell she had an unplanned pregnancy during a nursing degree? Then a child with life-limiting disabilities? That's a really hard path that from my experience includes many emotions that are, I guess, almost shameful to admit - bitterness, frustration, a sense of entrapment. My impression of her is of someone who is now dealing with an avalanche of pain from not just grief but regret. That kind of regret that only comes when the person is no longer here for you to 'put it right'. Everything she is doing seems kind of like bluster to cover that pain up.
