A coroner has has called for a change in the law to fence off garden swimming pools following the death of an 'adventurous' boy who drowned on his third birthday. Jack Rowe was found face down in his family's swimming pool in Upavon, Wiltshire, last July around 20 minutes after being reported missing to police. The toddler had been trying to reach a toy when he fell into the water, an inquest into his death heard. Three-year-old Jack Crowe died just days after celebrating his birthday with family (right) when he fell into their garden swimming pool . A coroner ruled the death as accidental after hearing how he 'never went near' the pool, according to relatives. Dr Clare Balysz, assistant coroner for Wiltshire and Swindon, said she was in 'little doubt' of what had happened, calling for a change in the law to make fencing off swimming pools mandatory. The inquest heard how Jack was being looked after by his older brother Harry, 20, on his birthday while his parents, Nigel and Olivia Rowe, were out. When Harry returned from the bathroom to find Jack no longer in front of the television where he had been watching a Peppa Pig DVD, he alerted his father and stepmother who later called the police. As neighbours began combing the village in search of the toddler one family friend glanced at the pool in the family's garden. There, she saw Jack's lifeless body at the bottom. He was airlifted to Southampton General Hospital but later died. Olivia and Nigel Rowe are now raising awareness and money for survival swimming classes for children . The family launched a wide manhunt around their home village of Upavon, Wiltshire, after Jack went missing from watching television. He was found in the garden of their home (above) 20 minutes later . Recording an accidental death, Dr Balysz said:  'There is very little doubt in my mind as to what happened. 'I think he was an adventurous little boy and when his DVD of Peppa Pig finished he decided to take himself off outside. A charity has been set up in Jack's memory by his parents . 'I think he fell into the swimming pool and he may have been reaching for his toy. 'Children do run off the whole time and I think it’s very unfortunate and a tragic accident what happened to Jack. 'There was no fence surrounding the swimming pool.' She cited Australian laws which enforce child resistant barriers, adding that she planned to write to the Edward Thompson MP, Parliamentary Under Secretary of State for Children and Families, to implement it. 'I know it’s too late and it won’t bring Jack back but if something can be changed as a result of this at least something positive can come out of it.' Jack's parents are meanwhile campaigning to raise awareness for survival swimming lessons for children. Speaking of his son, chartered surveyor Nigel Rowe said: 'Jack has gone and we loved him - and we still love him now. 'But we still see ourselves as very lucky to have had him and because he was just so wonderful for three years. We are lucky enough to still have Ella, Harry and Laurence. 'We have difficult moments but we can look at ourselves being lucky and being unlucky but our lives go on and Jack was the unlucky one, not us. 'He was so safe with the pool and it created a degree of complacency and that is something we will always have to live with but that is hopefully all going to change.' Recalling the moment she saw the toddler at the bottom of the swimming pool, Caroline Dale said: 'I walked around the pool and I was looking hard at the bottom and I could suddenly see the shape of a small child. 'I looked in from the edge of the pool and I could see Jack was face down with his arms straight by his side. 'The colour of his clothing blended into those of the pool.' Just three days earlier the family held a part for the toddler during which they said he never went near the water's edge. Mr and Mrs Rowe said while they were lucky to have had Jack for three years.

Jack's mother said she did not notice his body was in the water the first time she looked because she thought he would have floated to the top. 'I assumed that if he drowned he would have floated so I didn’t see anything in the pool and we went straight out to search the river instead. 'The little broom was floating and it had never been there before the party - it had remained in the pool since the party days earlier.' Paying tribute to her late son, she added: 'He was very outgoing, very confident, not mischievous but active. He was so easy and so kind. 'He didn’t like swimming. He loved his baths but the pool was too cold.' A post-mortem examination revealed Jack died from a cardiac arrest brought on by drowning in the pool. Detective Sergeant Jason Roberts from Wiltshire Police investigated the death and was ‘completely satisfied’ no one else was involved, describing it as ‘nothing more than a tragic accident’.
