It took 30-year-old Louise and her husband Andy six years to conceive. After such a long struggle, they're finally looking forward to meeting their longed-for baby and showing it off to their worried stepmum and health care assistant Olwen. Sammy, who's 23, is about to have her third baby. An undiagnosed condition drove a wedge between Sammy and her mum, when her bad behaviour was put down to teenage hormones, until a long-awaited diagnosis of endometriosis when she was 19 enabled them to build bridges.

When Jody, who's 29, and Chris, who's 32, arrive at Liverpool Women's Hospital, she'll be giving birth for the first time.

Meanwhile, Mormons Cameron, who's 23, and Hannah, who's 21, met through the church and married young. Their faith has taught them the importance of family, and they can't wait to become parents. They just need to get through labour first. And Lesley, who's 41, was desperate to become a mum but couldn't find a man who wanted to be a dad.
