Lauren, who's 33, and Rachel, who's 36, have one daughter together, who was conceived by a donor and who Lauren carried. Rachel always wanted to be a genetic parent too, but after an egg-sharing process failed and she had a miscarriage, she accepted that she may never be a genetic parent, and now Lauren is carrying their second child, as they plan to become a family of four. Laura, who's 37, and Paul, who's 40, were friends for years, and then love blossomed. Between them they have nine children and now they have another one on the way.
