Nothing beats the home life for Mary-Louise Parker.
“Becoming a mom is the best thing that’s happened to me,” Parker, 45, told PEOPLE at the 5th Annual Worldwide Orphans benefit gala in New York City Monday. “I’ll be the first to admit that it can be very hard to raise two kids, but I absolutely love it. I can’t imagine what my life would be without my children.”
Parker, already mom to William Atticus, 5, her son with former boyfriend Billy Crudup, adopted Caroline Aberash, now 3, from Ethiopia in August 2007. She says it was the “best decision I’ve ever made.”
