Can someone help me with psychosocial nursing diagnosis?

Hey fellow students, I really have trouble coming up with psychosocial nursing diagnosis for my care plan. I'm currently in OB and had a patient that was physically abused by her partner, who used heavy narcotics & alcohol daily, so now she lives with her grandmother. The baby is healthy and might be given up for adoption. The mother is 40 and has 4 kids already; various ages and jobs. So, I really don't know why should be priority for the child, Not the mother? This careplan is for the infant, not the mother, so its more difficult to come up with things. Ineffective parenting? ANy ideas are GREATLY APPRECIATED!
