Pamela Rauseo was stuck in traffic on a Miami highway Thursday when her 5-month-old nephew, strapped into his car seat behind her, stopped screaming - and she knew something was very wrong.
"That was a red flag for me, because the car was at a standstill and he'd had a little bit of a cold and I knew that he was congested, so I got really worried," Rauseo told CNN on Friday about her nephew, Sebastian de la Cruz.
It turns out that she had plenty of cause for worry. "I pulled over on the left, and I jumped to the back to check up on him, and he was out, he was sleeping, and I touched him to stimulate him. I got no response, so I took him out of his car seat and he was completely limp and turning purple. I tried to call 911, but I was just so nervous my hands wouldn't function."
But others did. Rauseo screamed for help, and fellow motorists on the stretch of concrete congested with vehicles responded.
Lucila Godoy was among the first.
"I was driving in the middle lane, she was in the fast lane, and all of a sudden I see her and she's screaming and she's holding the baby and she's putting it up and down," she told CNN. "I just stopped the car and jumped out of the car, and I asked her what was going on and we started working as a team."
The team grew. With the help of a police officer who showed up moments later, the women began performing CPR on Sebastian, who resumed breathing on his own.
