It was then they discovered they had a water baby on their hands.
Only ten weeks after the operation, her mother Sanam took her to a swimming session for infants.
Rosanna proved to be such a natural that now, at the age of two, she can swim without armbands and has even passed her 15-metre test. Last month she became the youngest participant in a charity swim for the British Heart Foundation, raising more than Â£1,000 by covering 100 metres in stages.
â€˜I am so proud of her,â€™ said 27-year-old Mrs Ogden at the family home in Chorley, Lancashire. After suffering breathing difficulties, Rosanna was diagnosed with rhabdomyoma â€“ a tumour attached to her heart. Although benign, it was blocking the flow of blood.
