Pittsburgh, Pennsylvania (CNN) -- Getting a 4-year-old to eat his lunch of pizza and applesauce on a recent Saturday afternoon wasn't exactly what Sam and Diane McMutrie thought they'd be doing after their three kids grew up. 

The couple, in their 50s, are raising Fredo after his birth mother in Haiti gave him to an orphanage. 

"In so many ways he's changed us," said Diane McMutrie. "I'm glad that he's here, I'm glad that we can make a difference in his life." 

"He makes us smile everyday, he makes us laugh, he says the cutest things and he's just now the love of our life." 

Fredo arrived in Pittsburgh six months ago -- just a week after the January 12 earthquake devastated his home country and destroyed his orphanage. 

The McMutries' daughters played a key role in getting Fredo out of Haiti and into their parents' lives. 

About two years ago, daughters Jamie, 30, and Ali, 22, were working at an orphanage in Haiti when they called with an unusual request: They wanted to know if their parents would be willing to adopt Fredo. 

It was the beginning of a long process -- and the McMutries didn't go into it with any illusions. 

"I don't consider ourselves special," said Sam McMutrie. "We just happen to be adopting a Haitian boy who our daughters love and thought it would be great for us." 

Sam McMutrie admitted he needed some convincing, but in the end, both he and Diane knew what they were getting into. 
Were they both immediatly on board?
