Rumer Willis Documents Daughter's 2-Month Doctor's Checkup

Rumer Willis is still in complete baby bliss after giving birth to her first child with boyfriend Derek Richard Thomas just two months ago.

Rumer, the eldest daughter of former celebrity spouses Bruce Willis and Demi Moore, welcomed her own baby girl to the world in April, and now it's already time for the little one's 2-month checkup at the doctors.

"I can't believe she's mine," the first-time mom gushed over her infant daughter, Louetta, in a new Instagram Story from Wednesday, June 28, which showed the bundle of joy resting in a baby carrier on the floor.

"Took our girl for her 2 month check up!" Rumer, 34, exclaimed in the IG Story, obtained by People. She also included a photo of Derek 28, holding Louetta's carrier while standing in the elevator and sipping on some coffee.

"Baby Daddy looking like a snack...??," she wrote across the pic.
