What would possibly drive a mother to take the life of her child? It seems almost unfathomable. But last week, 40-year-old Olga Freeman pleaded guilty to manslaughter due to diminished responsibility after suffocating her severely autistic ten-year-old son Dylan last summer. Described as 'a great mum', the divorced lawyer was said to be suffering some sort of psychosis at the time of the incident, triggered by the relentless nightmare of trying to care for Dylan, seemingly with zero help or support. I found the details of the case almost too painful to read, not least because I've long felt a sense of deep foreboding that something like this might happen.
