Op, go and adopt a young child wit pmld. Be a single parent and hold down a full time job. Try and do this with no support from anyone because the wait for the possible respite can be years, yes really years. Try to do this while going to various medical appointments, to other appointments begging for help. To have no sleep because of the complex needs of the child.
Oh wait, did. I say work full time? What was I thinking? You cannot work full time because finding childcare for a child below school age for a child with pmld is bloody hard. Never mind the impact on the time off for appointments. Exhausted because of a lack of sleep. The child is ill and requires time off.
Then come back and condemn her. She told them that she could not handle a disabled child, not everyone can. Even birth parents face this dilemma but without this type of judgement.
The person at fault is the person who placed the child with her, knowing her circumstances. Knowing that could not cope. That person failed her and a child that requires 4 carers. Yet that person was happy to place th child in a household of one.
Your judgment is clearly aimed at the wrong person.
