During the video, Samantha and her mother were shocked to capture Samantha’s newborn child crawling on camera.

“How is that even normal?” the creator repeatedly asked as she taped the unprecedented event. “She should not be this strong!” the baby’s grandmother exclaimed when she lifted her head.

Naturally, the mother-daughter duo were not the only ones confused by the occurrence. But never fear! There is a logical scientific explanation as to why a newborn infant possesses the ability to crawl.

On TikTok, Dr. Karan Raj — an NHS surgeon — stitched Samantha’s viral video with one of his own. “What this baby is doing is very normal,” Dr. Raj prefaced. “Tiny humans are pre-programmed with certain software updates for survival.”

The medical professional explained that one of these pre-programmed software updates is the “crawling reflex” or the “breast crawl,” a behavior infants exhibit when hungry and searching for a nipple to nurse on.

“If you put a baby on a mother’s tummy, it will crawl toward the source of milk like a homing beacon and latch onto the breast,” Dr. Raj said.
