A 27-year-old Canadian mother, Carolina Moreno, has shared the extraordinary story of how she unknowingly gave birth while asleep during labour.

Moreno described the experience as one of the most traumatic moments of her life.

In a video trending on TikTok on Tuesday, she revealed that she was not awake when her third child was born.

In the video, Moreno recounted how she was admitted for an induced labour after testing positive for Group B Streptococcus, a bacterial infection that required doctors to administer antibiotics before breaking her water.

Unlike her previous pregnancies, she said she was already three centimetres dilated with a thinning cervix when she arrived at the hospital, prompting medical staff to begin treatment immediately.
