 The custodial relationship involves a set of duties aimed at, and justified by, the welfare of the child. As custodian, the parent is under a limited obligation to work for and organize his or her life around the welfare and development of the child, for the child’s sake. Analysis of the content of parental responsibilities has therefore mostly focused on the rights of the child. Feinberg’s right to an “open future” can be read as a limit on parental discretion (see 5.1). It can also be interpreted as giving children positive claims to certain goods, such as an education that leaves them with a wide range of valuable life plans to choose from. Whether there is such a positive right and in what it consists are matters of dispute (Liao 2015; Mills 2003; Lotz 2006 and 2014; Millum 2014; essays in Archard and Macleod 2002; entry on  children’s rights).  Another question is whether parental responsibilities end when the child reaches adulthood, or whether they are lifelong (Weinberg 2018).
