Can I just add a point to this thread?
Whilst what happened to that poor baby was beyond disgusting, we don't know for sure what went on.
I followed the story at the time and from what I can remember the mother was a drug user, she didn't murder her son but his death was probably caused by neglect, the house fell into squalor after the baby died as she couldn't cope with what had happened/she'd done.
If you look closely at the photos you can see that it was probably once a nice house.
It is awful when a child isn't safe and protected by their own mother, however I think public services and the wider community also have some responsibility to notice when someone isn't coping.
