“Blue Ivy is relishing the role as a new big sister. She has been keeping mommy company in the hospital and has even helped in the naming process of her new siblings,” a source previously revealed. “Blue is happy and can’t wait to take the new babies home to play with.”

And it’s not just Blue who is doing well since the twins came home, the family is all-around happier despite the cheating rumors that were swirling between Beyoncé and JAY-Z.

“Jay’s at home more and is more of a family man. His focus is Beyoncé and the kids. It’s like a rebirth,” a source told In Touch, adding their move to the West Coast helped a lot. “They both love it. They are just all-around happier.”

We’re sure they’re all having so much fun together!
