A quick-thinking convenience store clerk snatched a baby out of the arms of a woman who suffered a seizure and collapsed to the floor.

Rebecca Montano, of Colorado, said she was playing with the 3-month-old baby while ringing up a soda transaction for the customer.

“I wanted to make the baby smile because I love babies, I am a mom and grandma,” she told Inside Edition. “I look at the mom and she has a blank stare and something in me said something wasn’t right.”

Store surveillance footage shows Montana leaping into action to snatch the infant out of the mother’s arms just as the woman crumpled to the floor.

“She started to sway so I grabbed the baby’s arms,” Montano said. “[The mother] was lost in space. I said, ‘I gotta take this baby’ and took the baby out of her arms. When I did that she started to fall.”

Another customer rushed over to tend to the woman while the store clerk called 911.

Montano and the woman was reunited on Wednesday.

“She came back yesterday afternoon… to tell me thank you for saving her baby,” she said.

Montano said the woman, who is in her 20’s, told her she’d suffered from seizures since she was a child.

“It was scary, it upset me terribly,” she said. “Every time I watch the clip I shake because I don’t like it. It brings tears to my eyes.

“Now I feel better because I know the girl is OK.”
