Rebecca Montano, a convenience worker in Denver, Colorado, was shown pulling the child away before her mother slumped backward and fell onto the floor.
She then handed the baby to another customer so she could call 911 and check to make sure the mother, in her early 20s, kept breathing during the seizure on Sunday.
Montano said the woman returned to the store to thank her on Wednesday and confirmed she had suffered seizures most of her life.
‘She came back yesterday afternoon… to tell me thank you for saving her baby,’ she added.
The store worker added she believed in ‘good karma’ and hoped if something like that ever happened to her, somebody would help her, too.
