First-time parents Laura and Ryan have to learn to cope with having two babies in the neonatal unit of Liverpool Women's Hospital's at once. Twins Max and Charlie were born 14 weeks early and both boys were making good progress until one contracted a life-threatening infection. Elsewhere, Dr Chris Dewhurst and his team begin a race against the clock to ensure that a baby is stable enough to have life-saving surgery, while Kaili has her labour artificially induced after her waters broke over six weeks early.
