Munn posted several shots of Malcolm on Mulaney's lap eating pieces of cake with his small hands. The toddler — wearing a white shirt with gray shorts and a knitted crown with a "1" on it — was quick to get messy, with pieces of chocolate smeared across his face and all over his outfit.

In an Instagram video in October, the mom of one asked followers for advice on how to get her son to take his second nap of the day as he was still riled up and crawling around the living room.

"He's trying to drop his second nap! 😩," Munn wrote on top of the clip, which shows her with her hand on her chin as Malcolm crawls away.

"He's too young to drop the second nap and I'm too tired for it to happen. How do I get him to nap?????" she captioned the video.

"While Malcolm wins the battle of the second nap, I'm over here with chapped lips and autoimmune breakouts...also I should brush my hair," she later wrote over a clip of her pointing to her face.
