Paper by Gerald Harrison & Julia Tanner, published on September 1, 2016 in The Philosophers' Magazine

They may raise questions about the number of children it's responsible to have or whether it's permissible to reproduce when there's a strong risk of serious disability. But in general, having children is considered a good thing to do, something that's morally permissible in most cases (perhaps even obligatory).
