Families come in all shapes and sizes, but for some reason the nuclear 'traditional' family is still seen by some as the way all families are meant to be. Susan Golombok is the Director of the Centre for Family Research at the University of Cambridge. She's been researching family units, and how children are doing, since the 70s. Her book We are family, what really matters for parents and children delves into the facts on what it takes for children to thrive. Susan talks about why single parents by choice, same sex families and other families that diverge from the 'traditional' model are proving that their way works too.
