Missouri teen credited for saving infant with CPR

A quick-thinking teen is being credited Monday for helping to save the life of an 11-month-old baby at a Missouri Walmart store.

A surveillance video shows a mother trying to help her infant daughter who stopped breathing. As store employees call 911, 17-year old Abby Snodgrass appears after hearing the commotion.

Snodgrass revives the baby using CPR she had recently learned in health class.

"The one thought that crossed my mind was what if this doesn't work, and I just had to push it out of my mind and keep going because I knew that's what I had to do," Snodgrass said.

The family released a statement to ABC News: "We are exceedingly grateful to the young woman who helped our daughter. Our daughter is home and healthy and we couldn't be more thankful."
