It's official: Theodore James adds even more cuteness to this picture-perfect family.

Ivanka Trump and hubby Jared Kushner shared a family portrait of their growing brood with their newborn son making his professionally shot debut front and center, where he's catching some Z's while being cradled in mama's famous arms.

Meanwhile, his older siblings Arabella Rose, 4, and Joseph Frederick, 2, got dolled up for the occasion and flashed their pearly whites to the camera. Well, Arabella did, anyway. Joseph decided to go the brooding route, but it works.

"Our first picture as a family of five! Thank you for all of the love and well wishes," the mom of three captioned the sweet shot.
