A girl from Bolton, who had a tumour removed from her heart as a baby, has become one of the youngest children in the country to swim 400 hundred metres.
Rosanna Ogden, aged 4, only started swimming because doctors told her parents it would aid her recovery from surgery.
When the youngster's family originally took her swimming, they found she could cover many metres without coming up for air. Her parents say her ability is a "miracle".
A little girl has helped a charity raise over half a million pounds even though she is only 3 years old.
We first met Rosanna Ogden last year when her parents took her swimming to help her recover after heart surgery.
Rosanna proved a natural water baby.
She's since gone on to represent the British Heart Foundation as the face of their little hearts campaign.
She's now credited with helping them raise over £500,000.
Rosanna and her family have been speaking to Tony and Rachel:-
Rosanna is helping to launch the British Heart Foundation's Little Hearts Campaign.
