At the Richboro Taco Bell, outside of Philadelphia, manager Becky Arbaugh wasn't working the lunch rush, but was around nevertheless.

She heard a scream coming from the drive-through window, followed by the harrowing words ‘call 911 the baby isn't breathing!'"

The phone would have to wait, as Arbaugh threw off her headset and rushed to see the situation. Just outside the drive-through window, she saw Natasha Long holding the lifeless blue body of her 11-week-old son Myles.

"The mom was panicked," Arbaugh told Good Morning America. "I told her to give him to me and I performed CPR. I was trying to calm her down and comfort her and reassure her that he will be fine."

"The baby finally started to breathe. The ambulance came pretty quickly and then they took over," Arbaugh said. "The EMT said I saved his life."

The circumstances could not have been more fortunate for Myles, because Arbaugh, a mother to four children herself, has already restarted the heart of her daughter a few times owing to medical complications.

In an emailed statement to ABC News, a spokesperson for Taco Bell said: "We are incredibly proud of Becky for her heroic act earlier this week. We are getting in touch to express appreciation for her quick actions and kindness."

As for her "Taco Bell family" GMA said that store members and those in other locations have showered her with messages of appreciation, while mother Natasha spoke with Arbaugh on the phone the next day to express what the mothers reading can only imagine would be heartfelt gratitude.
