A quick-thinking 10-year-old helped deliver her baby sister at home using vital tips from television's 'One Born Every Minute' - after she secretly watched the programme against her parents' wishes. Trinity Culley, from Fingringhoe, Essex, used the knowledge she gained from watching the baby-birthing programme which she secretly viewed in her bedroom after her mother told her it was too graphic. But when her mother Dee Culley's waters broke two weeks ahead of schedule, she sprang into action.

Whilst her dad Terry, 34, was on the phone desperately trying to arrange for a lift to hospital Trinity calmly collected towels and reassured her mum everything would be okay. Within minutes she had helped deliver her baby sister, Jasmin Elizabeth-Rose, who arrived in the family's front room weighing 7lb 1oz. Mrs Culley said: 'My waters had broken and my husband was on the phone to get his mum to take us to hospital. 'But by the time she got here, the baby had already been born. 'When it all started happening, Trinity turned to me and said: "It's OK mum, I have seen One Born Every Minute. I'll go get the towels." 'She was just amazing. Words can't express how proud I am of her. I think a lot girls of her age would not have been so calm and known what to do.' The 10-year-old  used the knowledge she gained from watching One Born Every Minute to deliver her baby sister (pictured together) Mrs Culley said she has since given her daughter a ticking off for secretly watching 'One Born Every Minute', the series set on a hospital's labour ward. She added: 'Trinity just turned and said to me: "But mum, if I hadn't, I wouldn't have known what to do".' Mrs Culley, who now has four children, described how her husband was on the phone to the 999 operator as she gave birth. She added: 'They asked him: "How far along is she?" and I could hear him saying: "She's got two weeks left". 'Then he was saying: "I can see a face, oh and there's a body". An ambulance arrived between five and ten minutes later, but we had pretty much done everything for them.' She and her newborn baby were checked over, but neither needed treatment. The couple have four children - Trinity, Jade, 2, Samuel, 1, and their new arrival Jasmin Elizabeth Rose, who was born on March 31. Trinity calmly collected towels and reassured her mother that everything would be okay after Mrs Culley's waters broke two weeks ahead of schedule .
