 This concern has been expressed in various different ways. Some, for example, suggest that selection motivated by such desires is incompatible with parental virtues such as ‘acceptingness’ (McDougall 2007), ‘openness to the unbidden’ (Sandel 2007), and ‘unconditional love’ (Herrisone-Kelly 2007). Those who take this view hold onto the traditional notion of the child as a gift and correspondingly suggest that parents ought to care, not about the traits that their children possess, but about developing a loving relationship with and raising whatever child they receive. Others take a more Kantian line, suggesting that such parents are wrongfully instrumentalising their children: treating them as a means of fulfilling parental hopes and dreams rather than as entities who, once born, exist for their own sake (Davis 1997).
