Proud Lisburn mum Lisa Allen and her own little hero, son Aaron (3) will be walking for Mencap NI at the charity's first Princess and Superhero Walk in Ormeau Park tomorrow.
It's a moment she thought would never happen until Aaron started attending the Mencap Children's Centre.
When Mrs Allen was 28 weeks pregnant with Aaron, she was told that he would have Duodenal Atresia, which causes intestinal obstruction - where the stomach and intestines are not joined together, and might also have a chromosome disorder.
Born with Down's Syndrome, a heart condition and congenital cataracts, Aaron had to have surgery on his stomach and intestines on the day he was born.
At 10 weeks, Aaron had eye surgery, and two weeks later he had heart surgery. For a period he had to be isolated from other children and he has to wear hearing aid.
"Aaron had seven surgeries by the time he was two, he seemed to be constantly in surgery or recovering from operations.
"It was a difficult time, as every operation was so serious, it was a constant worry about what to do. Then Aaron got a place at the Mencap children's centre when he was two.
"It was unbelievable, Mencap changed our lives and empowered us to look after our child, we would have been lost without them," said Mrs Allen.
Mencap's Superhero and Princess Walk will help raise funds to support the charity's Belfast centre, which works with 52 children a year, aged two to three with a learning disability, autism and global developmental delay.
