The proud mother captioned the photo with, “Dry Runs,” and showed her 5-year-old little girl practicing how to change a diaper on a toy doll.
The 37-year-old Grammy winner took to Instagram in early November to announce she was expecting her second child with husband Carey Hart.
While the singer hasn’t been posting much of her growing baby bump on social media, she did post a Boomerang video of the bump after Thanksgiving.
“Late turkey dance love from The Harts #gratitude #loveyourself #loveeachother #morepie,” she captioned the video.
“I have lived a lot of life in a very short time, and you get hardened a little bit — you get jaded, you build up walls. And when you see this little kid, and you get to watch them through infancy to toddler to little person, it’s amazing,” the singer previously told PEOPLE about motherhood.
“You see how you were. When you watch this bundle full of love and light that’s untarnished and untainted by heartache and any of the numerous things that change you, it’s very healing. It’s a miracle.”
