Alyson Hannigan has reached a major parenting milestone, and her latest family photo has fans doing a double take.
The How I Met Your Mother star, 52, shared a rare photo of her youngest daughter, Keeva, 14, as the teenager headed off to high school, proudly revealing that she now has two high schoolers at home.
In the sweet snap, Keeva stood outside the family's home holding one of her mom's homemade back-to-school signs, which read: "So high school, class of 2030."
"Back to school means back to sign making!" Alyson captioned the post. "I obviously had to reference my favorite Taylor song since I now have 2 High Schoolers," adding a wide-eyed emoji.

"She's your twin, Aly - how beautiful," one follower commented, while another Buffy the Vampire Slayer fan admitted: "I thought she was young Willow for a moment."
The resemblance has been noted before. When Alyson shared photos celebrating Keeva having her braces removed last year, followers similarly described the mother and daughter as "copy and paste" and joked that they looked more like sisters.

Alyson shares Keeva and her older daughter Satyana, 17, with her husband of more than two decades, actor Alexis Denisof. The couple met through Buffy the Vampire Slayer, in which Alyson famously played Willow Rosenberg while Alexis appeared as Wesley Wyndam-Pryce, and married in 2003.
They welcomed Satyana on March 24, 2009, which happens to be Alyson's own birthday, followed by Keeva on May 23, 2012.

Alyson has previously admitted that she can see elements of herself in her eldest, particularly when it comes to their shared interests.
"I see parts of me [in her]," she said of Satyana when she was younger. "I definitely see so many similarities. The books that I loved, she loves."
Keeva, meanwhile, has previously shown an interest in performing, although Alyson has been determined not to push either of her daughters towards Hollywood.
"Obviously, I'll support whatever they want," she has said, explaining that she wanted her daughters to "be children for as long as they have."
Alyson Hannigan on raising teenage daughters
Now that both girls are teenagers, Alyson has been candid about how her role as a mom has evolved.
In 2025, she reunited with former Buffy co-star and longtime friend Sarah Michelle Gellar to discuss the particular challenges that come with raising teenage daughters.
Alyson revealed that she regularly turns to Sarah, who is also raising teenagers, when she needs parenting advice. "I always usually call her," Alyson said, while Sarah revealed that the advice flows both ways between the two longtime friends.
The actresses also spoke about the responsibility they feel as their children become more independent and begin making decisions about their own health and futures.
For Alyson, motherhood has long taken priority over her career. After How I Met Your Mother ended in 2014 following nine seasons, she deliberately spent more time focusing on family life and raising her daughters. "Being a mom is simply the best thing I have ever done," she once said. "My kids make me laugh and smile every day."

The actress has also spoken movingly about how becoming a mother transformed her life. "[Being a mother] has changed me in every way because my life is so much greater," she previously told Us Weekly. "It filled a void I never knew was there - it's the most amazing experience of my life."
She has particularly cherished watching the relationship between her daughters develop.
When the girls were little, Alyson revealed that Satyana immediately embraced becoming a big sister and would even hum lullabies whenever baby Keeva became upset. "It melts your heart, the love that they have for each other," she said at the time.
More than a decade later, the sisters are entering another chapter together. And Alyson's disbelief at having "2 High Schoolers" appears to be shared by her followers, with one fan admitting that seeing "Class of 2030" on Keeva's sign made them realize just how quickly the years are passing.
