Having a newborn is hard enough as it is, but add in a set of twin newborns who look identical in addition to double the newborn sleep deprivation and you can find yourself in quite a predicament. Like this twin mom, who had to enlist the help of the police when she couldn’t tell her newborn sons apart.

“Tomorrow I have to go to the police to have my twins fingerprinted so they can tell me which one is which,” Sofia Rodríguez, 25, of Córdoba, Argentina, recently tweeted. “I won the ‘Mother of the Year’ award.”

Rodríguez also shared some photos of her twins, Valentin and Lorenzo, and explained that while the boys look a little different from one another in pictures—”in person, they are the same.”

“I never thought I would get them confused—Valentin always (wore) a blue ribbon, but when I realized that it was too small for him, I decided to cut it (off),” Rodríguez tells TODAY.com in a translated interview.

She was apparently changing the boys out of their onesies when confusion set in and the panic hit.

“It was crazy,” she says.

Shortly after, she asked the police to have her babies fingerprinted in order to tell them apart—though the fingerprints didn’t look very “defined,” according to Rodríguez.

Thankfully on March 15, Argentina’s National Registry of Persons will identify the boys through their fingerprints.

Though identical twins are never completely identical thanks to physical differences like birthmarks, freckles, moles and other features—it can still be incredibly difficult to tell them apart, especially when they’re brand new and may not have any of these features.

As time goes on and personalities develop, it should become easier to tell one twin from the other. TODAY suggests colored bracelets, name tags, pierced ears, a painted toenail (with nontoxic polish), or using assigned seating in the car.

Thankfully for Rodríguez and her boyfriend, the twins should be identified from one another this week. And many twin parents on social media have reached out to her to share their own similar stories—an amusing but important reminder that none of us can get it right 100% of the time.
