The first episode focuses on preparations for birth and the shock of the arrival of a new baby. Sam and Rob from Machen are expecting triplets and are stocking up with hundreds of nappies, wipes and other supplies. Most triplets are delivered premature, and theirs will be no exception. In Burry Port, Cathy and Andrew are counting on being among the three per cent of parents who have a homebirth. Kelle and Ali from Cardiff have a very lively household: two dogs and a cheeky four-year-old daughter Ayla. And Kathryn and Richard from Ammanford are a couple with a master plan, with all the elements of the pregnancy plotted with military precision.
