Two couples prove that unplanned pregnancies can happen at very different ages. Andy, who's 41, and Nina, who's 39, thought they'd left nappies and sleepless nights behind long ago. With their children Danielle, who's 14, and Lewis, who's 10, b... (more)ecoming increasingly independent, they'd just started to get their own lives back again: going out, holidaying and enjoying life. They all got the shock of their lives when Nina announced she was pregnant with twins. The kids were initially appalled that their parents could be so irresponsible but soon embrace the idea of baby siblings and cheer their mum up with fun and games while she waits for her Caesarean. Jonathan, who's 21, met 18-year-old Laura when he randomly sent her a message on a social networking site. Three months later she fell pregnant. While Laura panicked, Jonathan was delighted: starting a family has been his sole ambition since the age of ten. Having developed gestational diabetes, Laura is booked in for an early induction and the couple prepare for a long wait. Jonathan gets on Laura's nerves with his almost constant chatter but when their baby's heartbeat drops and Laura is rushed to theatre, Jonathan's joking around is quickly replaced by overwhelming concern.
