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 Andy's worried stepmum Olwen, who's a health care assistant at the hospital. 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.

Louise is having her first child at 45, after fearing for years that she might never experience motherhood. But she's had a heart-breaking split with her baby's father, Dan, and they haven't seen each other for a few months. They both have a lot of soul-searching to do as he arrives to support her during labour. Jess is 16 and has always wanted a sibling. Her mum Elaine and stepdad Jeff found it difficult to conceive, but now Elaine is at Liverpool Women's Hospital to give birth, and her labour is an eye-opener for Jess, who says she's 'scarred for life'! Fang and Zhaoliang both grew up under China's infamous one-child policy, so neither of them has a sibling. A surprise pregnancy is a 'beautiful accident' that will give their son a welcome playmate and bring balance and harmony to their family.
