The idea that families come in all shapes and sizes has never been more true with adoption, same-sex relationships and the introduction of new ways to conceive.
Writer Samuel Leighton-Dore, 25, spoke to Mirror Online about his decision for his sister to have his child - and has opened up about the negative response it has received.
Samuel, from Sydney, is in a relationship with photographer and designer Bradley Tennant but doesn't want to miss out on their baby having both of their family's genes.
