Actor Colin Farrell opened up about life raising a child with disabilities.

Farrell’s oldest son, James, 9, was born with Angelman Syndrome, which is a “neuro-genetic disorder with symptoms including intellectual and developmental disability, seizures, jerky movements and sleep disturbances,” the Daily Mail reported.

The proud father told In Touch magazine, in an interview that will appear in its December issue, that he and James’ mother model, Kim Bordenave, especially appreciate his milestones.

“We share in the smallest victories; the first words at age six or seven, being able to feed oneself at 19, and getting the seizures under control. When James took his first steps at age four, I nearly broke in half!”

Farrell said the 2007 Shanghai Special Olympics inspired him to speak publicly about how much pride his son has given him.

He has also been involved with the Foundation For Angelman Syndrome Therapeutics,  from which he receives moral support.

“When you're the parent of a child with special needs, it's important to feel that you're not alone,” he told In Touch.

“He has enriched my life, but I don't want to minimize the trials that so many families go through; the fear, consternation, frustration, and pain.”

The actor, once known as a bad boy, interviewed with Men's Health magazine in September, and said becoming a father encouraged him to change his ways.

“What my first son James did was allow me to care for something in this world when I couldn’t care for myself. James saved my life,” he said.

Farrell has another son, Henry, three, with actress and singer, Alicja Bachleda-Curus.
