This is really depressing. Didn't realise the mother was on heroin. What hope has that baby got?
It just goes round in circles and carries on from one generation to the next.
I don't believe the baby should be taken from the girl outright. She deserves a chance to be a mother.
I feel the best thing would be to take both the girl and the baby into a mother & baby foster placement where she can be taught parenting skills from a skilled foster carer. She has obviously never been taught to parent from her own mother.
Obviously, if she fails, the best thing for this baby probably is adoption, to allow it a chance in life, but I think she could be given a chance.
There was (I think a) 12 yr old who was pregnant a couple of years ago. There was a follow up to her case in a magazine a few weeks ago. She seems to be coping okay with her child and has now had a second (not a good thing probably.....) but the children appeared well cared for.
Very sad for everyone involved, especially the baby 
The girls mother should be ashamed of herself 
Shooting up heroin in the kitchen and allowing it to be photographed for the Sunday papers??? I think ss should be looking very carefully at what happens to all her children.......
