When a pregnant parent is asked about the identity of their unborn child, they will often say that it does not matter except that the baby is healthy. Unsaid for fear of taboo, the covert preferences and biases of a parent may cause disappointment when brought into fruition. The infant may be the ‘wrong’ sex, ‘wrong’ ability, ‘wrong’ appearance; there is no guarantee that even the primary request (for a healthy child) is fulfilled. Until recently, a distraught parent could do little but abort the pregnancy or live with their imperfection. Now, there is potential for every child to be ‘perfect’ – a ‘designer baby’.
