This mom deserves the "Reflexes Like A Rattlesnake" Award for 2019. Chalk this up to one of every parent's worst nightmares.

This video starts out with a mom and her toddler daughter exiting an elevator. She's holding her hand, and when she lets go the kid immediately heads to the railing, loses her balance, and starts falling through.

Thankfully, the mom grabs her leg at the last possible second and pulls her back.
