Following the conclusion of Good Luck Charlie, Mia has landed a few more acting gigs. According to her official IMDb page, she starred in two short films: Shadow Theory and Photographic Memory. Mia most recently starred as Paige in the Brat TV original series Mani and appeared in one episode of the TV series Conrad.

On Aug. 23, 2023, Mia set the internet ablaze when she took to Instagram and announced she started her first year of high school. She posed in front of several palm trees and held a colorful sign that read, "First Day 9th Grade."

As expected, a torrent of reactions to the post expressed disbelief.

"Damn, we are getting old," one person said alongside a loudly crying emoji. "I remember watching you on TV when you was just a toddler." Another wrote, "High school? Where in the world did all the time go?"

Mia's TV mom, Leigh-Allyn Baker, also commented on the post with several crying emojis: "She's so big! Mia, you're beautiful!" Mia replied, "Thanks, Mama Leigh." OK, is anyone else desperate for a reunion?!

The news quickly spread to other social media platforms, including X (formerly known as Twitter) — and it's safe to say everyone (which includes us) was feeling really, really old.

"This post just called me old," one person wrote on X, while another sadly said, "I can't really be this old."

A third person hilariously posted, "Alright pack it up folks, we're off to the nursing home!"

"Oh, I'm an old hag," someone else shared. Honestly, we agree — we've felt really old lately, and unfortunately, Mia's post just confirmed our worst nightmare — we're not getting any younger!

Another person penned, "Already feeling old but then checking the quotes and seeing people surprised that they're older than her ???? This app is turning into a daycare, my god."

On the other hand, some X users were so happy to see Mia thriving.

"Omg, she's grown so much!" one person pointed out on X. "I can't believe she's already a teenager!! Sending her lots of love and success!" Someone else added, "She grew up so fast! Congratulations to her!"

Unlike us, some people quickly accepted that Mia is in high school: You know what? I'm OK with this," a person said. "I thought y'all were going to say she started college today or something, that would have made me feel really old."

Well, we're off to tour several senior living communities!
