The thing is I think she did have a lot of support previously with the other births... including a place in a mother and baby facility which she wouldn't take up. She also abandoned one of her other babies while they were still in hospital after the birth. She gave fake names when attending hospital... the list goes on!
Her family hired private investigators and worked closely with SS as they were so worried about the children.
Personally, I think she put her own relationship with MG before that with any of her children. Out of just about anyone she had the opportunity to be able to keep her children - money, family support etc and the opportunity to undertake programs which were designed to keep her with her child. To have four children removed there has to be something very seriously wrong. And evidently there was with the death of her fifth.
Jurors have been told they will hear evidence from the couple's family court proceedings next week, which may shed more light on this aspect.
