Being a good parent is harder now than it has ever
been before. In pressurised modern lives, demands to be a fulfilled individual,
and a good partner and a good worker, take no account of being a good parent. We
haven’t left space for the nurturing parents expect to provide and children
need. As a result, many parents in the western world just don’t work. Something will have to change. With luck, people in the future will only have children if they really want them. And that should mean that parenthood is seen as a much more positive commitment than it is now, and that parents are socially supported, and admired for doing a good job.
