Not the child's needs. Life.
I don't think there are any considerations that justify murder of a child...except in rare cases, when carrying that child will potentially kill the mother. Not via the regular risks of childbirth, because abortion carries pretty much the same potential of death and illness, but for a very specific reason..the mother is a brittle diabetic, the mother is in need of cancer treatment, or she has some unspecified illness or disorder that would result in her dying if she carried a child to term. I honestly have no idea, aside from renal or liver failure, diabetes, and cancer, what might fit that description, I just know it's extremely rare.
A child can't have NEEDS unless it's alive, and except for life, a mother has no NEEDS that trump another's right to LIVE.
