So cute!

Just days after she welcomed her son, Maddox, Allison Holker took to Instagram to share the first photo of her little boy — and the snapshot is too precious!

"Our Maddox is like the beginning of all things — wonder, hope and a dream of possibilities. My life and our family's home is changed forever," the Dancing with the Stars pro, 28, wrote alongside the sweet black-and-white photo of herself holding Maddox's hand on Sunday, April 3.

"He blessed our lives exactly a week ago and it will never be the same again, and he has brought such a beautiful joy with him. We will let every moment sink in and last a lifetime!" the caption continued. "This is our family, our happiness and our future. We will love you forever Maddox Laurel Boss."
