On cue! Jenna Fischer's 5-month-old daughter Harper has already mastered the selfie. In an Instagram posted by Fischer on Wednesday, Oct. 29, the adorable little girl smiled for the camera while resting in her mom's Baby Bjorn carrier.

 

"Been up since dawn. Cookies will help! #bakingday," the Office alum captioned the photo, where she's grinning from ear to ear sans makeup.

As previously reported by Us Weekly, Fischer became a second-time mom this past May. In a statement the actress and her husband Lee Kirk gushed: "We are pleased to announce the birth of our daughter Harper Marie Kirk. Born May 25, 2014. The family is doing great. We are happy, healthy, and sleepy."

Leading up to the arrival of her daughter, she humorously tweeted about the "nesting phase" of her pregnancy, sharing with followers, "Yesterday, I dusted the pipes in my basement."

Kirk and Fischer are also parents to 3-year-old son Weston.
