In the hit NBC/Fox sitcom Brooklyn Nine-Nine, Amy Santiago, portrayed by Melissa Fumero, becomes pregnant during the show’s seventh season. She gives birth to a healthy baby boy named Mac in the Season 7 finale, titled "Lights Out." This development serves as a pivotal moment for her character and her relationship with Jake Peralta.
The journey of Amy Santiago from a competitive, hyper-organized detective to a high-ranking officer and mother is one of the most celebrated character arcs in modern television. While many sitcoms treat pregnancy as a sudden plot device, Brooklyn Nine-Nine took a grounded, often emotional approach to the subject. As of 2026, the show remains a staple of streaming platforms, and fans continue to revisit the "Peraltiago" family milestones with great affection.
The Evolution of Peraltiago: From Rivals to Parents
To understand the impact of Amy Santiago's pregnancy status, one must first look at the foundation of her relationship with Jake Peralta. What started as a competitive workplace rivalry in Season 1—complete with a bet over who could rack up the most arrests—slowly evolved into a deep, supportive romance.
By the time the couple married at the end of Season 5, the question of children became a looming topic for the writers. Unlike many sitcom couples who agree on children immediately, Jake and Amy had a significant "Hubbub" (as Jake called it) in Season 6, Episode 12, titled "Case Gentle." They realized they hadn't actually discussed whether they wanted children. Amy, true to her character, had a structured timeline, while Jake harbored fears stemming from his own father's absenteeism.
This internal conflict set the stage for the pregnancy arc in Season 7. Once they decided they were ready, the show didn’t gift them a "sitcom miracle" pregnancy immediately. Instead, it explored the realistic and often frustrating process of trying to conceive.
The "Trying" Arc: A Realistic Look at Conception
In Season 7, Episode 6, titled "Trying," the show dedicated an entire episode to the passage of time as Jake and Amy attempted to get pregnant. This episode was widely praised by viewers and critics for its honest portrayal of the emotional toll that infertility and difficulty conceiving can take on a couple.
The episode spans six months, showing the couple’s transition from excitement to clinical mechanicalness, and finally to sadness and frustration. Amy’s "Type A" personality is put to the test as her meticulous tracking, temperature taking, and scheduling fail to produce a positive pregnancy test. This narrative choice was significant because it humanized the characters and resonated with many audience members facing similar struggles in real life.
The arc concluded with the couple deciding to take a break from the pressure, which led to the eventual reveal that they were finally expecting. This storyline solidified the bond between the characters, showing that their partnership was capable of weathering disappointment and biological hurdles.
The Pregnancy Reveal and Development
Amy officially reveals she is pregnant in the latter half of Season 7. Throughout the remainder of the season, the show balances the humor of Amy’s pregnancy symptoms with her continued professional ambition. Amy Santiago would not be herself if she let a pregnancy slow down her career goals, and the writers maintained this consistency.
During her pregnancy, Amy is seen navigating her duties as a Sergeant. The show avoids the trope of the "fragile pregnant woman," instead opting to show Amy as capable, if occasionally hormonal or physically uncomfortable. This period also allowed for comedic exploration of Jake’s "nesting" instincts, which were predictably over-the-top and influenced by his love for action movies.
The Birth of Mac: The Season 7 Finale
The climax of Amy Santiago’s pregnancy occurs in the Season 7 finale, "Lights Out." In classic Brooklyn Nine-Nine fashion, the birth happens under the most chaotic circumstances possible.
A massive blackout hits Brooklyn, sending the precinct into a frenzy. While Jake and Charles are out on the streets dealing with the chaos and attempting to stop a duo of high-end bank robbers, Amy is left in charge of the precinct. As the stress of the blackout reaches its peak, Amy goes into active labor.
Key Moments from "Lights Out":
- Amy in Command: Even while experiencing intense contractions, Amy refuses to relinquish control of the precinct. She manages the deployment of officers and the logistics of the blackout from a tactical chair.
- Jake’s Race Against Time: Jake and Charles spend the majority of the episode trying to navigate the gridlocked city to get back to Amy. They eventually resort to a pedal-powered "party bike" to make it to the precinct.
- The Birth: Amy eventually gives birth at the precinct with the help of firefighters (much to the chagrin of the police officers) and her colleagues.
- The Name: The baby is named McClane "Mac" Peralta, a direct tribute to John McClane from Die Hard, Jake’s favorite movie and his ultimate hero. Surprisingly, Amy agrees to the name, signaling her growth and her love for Jake.
Behind the Scenes: Melissa Fumero’s Real-Life Pregnancies
A point of confusion for many fans is the difference between Amy Santiago's pregnancy and the actress Melissa Fumero's real-life pregnancies. Melissa Fumero was actually pregnant twice during the filming of the series, but only one of those pregnancies was written into the show.
Comparing the Two Pregnancies
| Detail | Season 3 Pregnancy (Real Life) | Season 7 Pregnancy (Show & Real Life) |
|---|---|---|
| Status in Script | Hidden / Not part of the story | Written into the plot |
| Actress Status | Pregnant with son Enzo | Pregnant with son Axel |
| Production Tactics | Large bags, desks, and "prison jumpsuit" | No hiding necessary; integrated into arc |
| Key Episode | "Greg and Larry" (Undercover arc) | "Lights Out" (Birth of Mac) |
| Timeline | 2016 | 2020 |
In Season 3, the production team went to great lengths to hide Fumero’s bump. They used the classic sitcom trick of having her carry large folders, sit behind desks, or wear bulky clothing. Ironically, they eventually put her character in a fake pregnancy suit for an undercover mission in a women's prison, which allowed her to stop hiding her actual bump for a few episodes.
In Season 7, however, the timing aligned perfectly. Both the character and the actress were pregnant, allowing for a much more natural performance and avoiding the logistical headaches of hiding a physical change.
Parenthood in Season 8: Balancing the Badge and the Baby
The final season of Brooklyn Nine-Nine deals heavily with the aftermath of Mac’s birth and the realities of working parents in law enforcement. Amy and Jake face the "parental guilt" common to high-achieving professionals.
Amy’s career continues to skyrocket as she spearheads a major police reform program. Meanwhile, the couple struggles with childcare, sleep deprivation, and the fear that their dangerous jobs might prevent them from coming home to their son. This tension culminates in the series finale, where a major life decision is made regarding their family structure.
Jake's Evolution and the Ultimate Sacrifice
The most significant impact of Amy's pregnancy status on the show's conclusion is Jake Peralta's decision to leave the NYPD. In the series finale, "The Last Day," Jake reveals that he is resigning from the force to become a stay-at-home dad.
His reasoning is deeply tied to his desire to be the father he never had. He realizes that Amy’s career in police reform is vital and that she has the potential to reach the highest levels of the department (eventually becoming Chief). By choosing to stay home with Mac, Jake completes his transition from an impulsive, self-centered detective to a selfless, devoted father.
The Cultural Significance of Amy's Journey
The portrayal of Amy Santiago’s pregnancy and subsequent motherhood is often cited as a benchmark for how sitcoms can handle "changing the status quo" without losing the essence of the characters.
- Maintaining Ambition: Amy did not lose her professional drive. Often, female characters are sidelined or "softened" once they become mothers. Amy remained the smartest, most organized person in the room, using her parenting skills to improve her management style.
- The Role of the Father: The show emphasized that parenting is a shared responsibility. Jake was not a "bumbling dad" trope; he was competent, caring, and ultimately willing to prioritize his son’s needs over his own career ambitions.
- Realism in Sitcoms: By addressing the difficulty of conceiving, Brooklyn Nine-Nine provided a voice to a common but rarely discussed struggle, adding a layer of depth to what is primarily a comedy.

Final Perspective for Fans
