Pink Shares Sweet Photo of Daughter Willow Cuddling With Her Baby Brother

Little Willow is ready to take on her big sister duties!

Just days after introducing her second child, son Jameson Moon Hart, to the world, Pink uploaded a sweet Instagram photo of her 5½-year-old daughter Willow Sage holding the infant.

“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.

Pink and her husband Carey Hart welcomed baby Jameson on Monday, Dec. 26. The singer broke the news via social media on Wednesday.

“I love my baby daddy,” the singer, 37, captioned a photo of Hart holding their newborn.

She later uploaded a picture of Willow diapering a baby doll, writing, “Dry Runs.”

Pink and Hart, who have been married for more than a decade, told PEOPLE in December that they decided to not find out the sex of their baby until his arrival.

“I just want a healthy baby. That’s all I care about,” Hart said then. However, he added, “We got one princess, so hopefully we’ll have a little guy coming.”

Well, Hart got his wish! And the couple said they were excited to get back into caring for a newborn.

“It’s been a while since we’ve had a baby around the house,” he said then. “It’s going to be really fun.”
