"Integration is not easy for any family, so it took baby steps in some areas," McCarthy, who has son Evan, told E! News exclusively of her and her hubby, who also has two sons, Elijah and Xavier.
The 42-year-old added, "We talked about this last night. We said, 'It's funny how we can see how each child is a blessing for each other.' Like Evan is so influenced by Elijah, Donnie's son who's his similar age. And how Elijah means to me in my life that I didn't necessarily get from anybody before. So if everyone can just realize that integration is for a reason and you look at it like blessings, it makes it so much easier to just accept what is and kind of go through those bumps and grinds with peace."
When asked whether she wants to have more kids or if she's satisfied with three boys, McCarthy cracked that she's just waiting for her little ones to turn 18 and move out of the house!
"When you work so hard and your kids are out of the diaper phase, out of the high chair and you get rid of all that stuff...to start over again? No way!" she dished. "I want to go towards the light with my husband while we still can walk."
