Support for New Adoptive Parents

The Minister has made the point, which I accept, about how, for health reasons, benefits for parental leave and maternity benefits were decided on for employment and self-employment. The principle seems to have been established for adoptive parents in employment, too. What I have not followed from his argument—I waited until the end to ask, to see whether he fleshed it out—is the rationale for saying that the principle has not also been established for adoptive parents in self-employment.
