Following six families over their first laughter, love and chaos-filled weeks of parenthood, it provides a window into modern family life. From young parents dealing with an unexpected pregnancy to a gay couple and their surrogate who have planned everything in intricate detail; from the Surrey family who are adding a fifth to their brood of pre-school children to the remote Northumberland farmers whose due date is in the middle of lambing season; this series features a broad range of families from across Britain, united by one thing: they're all having a baby in 2019.
