The mother of a four-year-old girl who is in urgent need of a new heart is desperately appealing to parents to donate their child's organs if they ever find themselves in the "pure heartbreak" of a tragedy.
Little Holly Carroll started back to school last week, from her hospital bed at Our Lady's Children's Hospital in Dublin where she has lived since she suffered full heart failure in April 2017.
Since then, her mother Jessica O'Mahoney has had little toddler Albie (18 months) who is also now growing up in the hospital at his sister's constant bedside with his parents.
Holly, from Clonmel, Co. Tipperary, was born with Hypoplastic Left Heart Syndrome in January 2015 and underwent two major open heart surgeries in her first year of life to give her half a heart do double the work.
Although hooked up to feeding tubes and cannulas, the little fighter is constantly positive and wants nothing more than to be able to run really fast.
Her only hope is a transplant in Great Ormond Street in London and those hopes were already dashed once in October 2017 when a transplant couldn't go ahead because Holly's white blood cell count was too low.
Her parents Jessica and Jamie Carroll are now desperately appealing to parents to make the decision to donate their child's organs in the event of a tragedy.
"Congenital Heart Disease has stolen Holly's future and without a transplant, we will never get to see our girl grow up and have the best life she deserves," said Jessica.
"Because of the pressure on her half a heart to do the work of the missing pieces, Holly is now in full heart failure. Doctors say her heart isn't even beating anymore, it's just rocking. She urgently needs a new heart.
"It's not normal for a little girl to only know feeding tubes, broviacs, cannulas and all the other equipment but this is the nightmare that we are living until that call comes to say they have found our girl a shiny new heart
"We would never wish tragedy on anyone but as desperate parents who want our own child to survive, we are urging other parents to have that chat, in case an accident does happen.
"If you have a chat now, it might make it easier to say yes to donation, God forbid anyone finds themselves in that moment of pure heartbreak.
"Organ donation, especially children's are extremely low. If you can save lives, you are a hero. Please, be a hero and text Donor to 50050."
