In a series of sweet Instagram Stories posts shared on Friday, Nov. 8, the Newsroom actress posted clips of herself feeding and burping Méi. In the first video, Munn asked the newborn if "we should take videos of ourselves."

She added in text on the screen that Mulaney was "running after" Malcolm all day, joking that she had to take videos without his help.

"Me and my girl," she said as she fed Méi her bottle. In another clip, Munn wiped Méi's mouth and adjusted her green-striped outfit before burping her. "You're so cute, you're so little," she told her daughter, whom she also called "a squishy squishy baby" in text over the clip.
