The Scary Movie actress gave birth to Jack nine weeks early in 2012 and the pair spent the first month at his side while he remained in intensive care.
During that upsetting time, they turned to their faith to will Jack to get healthy.
The Guardians of the Galaxy star tells People magazine, "We were scared for a long time. We prayed a lot... It brought me closer to my family and it restored my faith in God, not that it needed to be restored, but it really redefined it. It showed me who in my life is really close to me."
Jack will turn two next month (Aug14).
