I see it a bit differently.
I think it was a tragic set of circumstances where the childminder didn’t foresee quite how high the girls needs were and didn’t know her well enough to gauge the level of risk.
The childminder did make it clear she was out a lot with the children. That’s not her fault; if I was using a childminder that’s one of the things I’d want.
The mother had to work and needed childcare.
So really what the little girl needed was specialist childcare, which is what I hope may happen as a result of this. I’m not blaming anyone; it’s just a horrible tragedy.
