In The World Of "Brooklyn Nine-Nine."

The "Amy Santigao" character is played by Melissa Fumero. Melissa Fumero has three children.

We know this due to her uncanny ability to be 4-7 months pregnant during the filming of every season.

A big part of the storyline of the show  this will they, won't they relationship between Amy Santiago and "Jake Perlata." Played by Andy Samberg.

Amy & Jake start dating in Season 3. Which was the first season in which Melissa Fumero decided to become pregnant.

After a few months of trying to hide it behind bulky costumes, big bags and standing desks. They finally decided;

"F'ck it. We're not the sort of show that needs to explain why his brand new girlfriend is already, clearly, pregnant."

So just went ahead with the script about the cruise ship that made her stick out in beachwear.
