“Happy New Year … the harts thank you for your love and we send it back to you in spades,” Pink captioned the photo of Willow sporting a wide grin as she held her new little brother in her arms.

The kids are all snugged up on a stormy Friday afternoon. Not gonna lie, saying that @pink and I have “kids” makes me a lil nervous and very grown up. And I wouldn’t change it for anything in the world. #MyWifeDidGood #SheCooked2GoodOnes
