  But it is far from obvious that this is the case (de Melo-Martin 2017). Clearly, common morality requires that prospective parents care about their children’s wellbeing, not that they maximize it. Moreover, in ordinary life, parents are not required to choose between child A and child B in virtue of which one is more likely to have the best life. Rather, when prospective parents make decisions that are likely to have an impact on their children’s welfare, such decisions involve comparisons between the life of a child if one does A or if one does B (e.g., if one promotes music training or sports).
