Sharista Giles, from Sweetwater, Tennessee, was five months pregnant when she was involved in a car accident while driving home from a concert in December with friends.
Her injuries were so bad doctors thought she would die.
While she was in a coma, doctors were forced to deliver her baby boy early and when he arrived in January they called him simply Baby L.
But on Wednesday (April 8), Sharista miraculously opened her eyes for the first time – and saw her little boy.
The young mother's family told ABC News that she opened her eyes, and soon began following her father's movements around the room.
Then, her father showed her a photo of her son.
Sharista's mum Beverley said: "He showed her a picture of her baby, and she followed the picture.
"When he turned around to put it back on the bulletin board, she turned her neck, her whole head trying to follow and find the picture again."
Baby L meanwhile is doing well, but is still in the neonatal intensive care unit at the University of Tennessee Medical Center.
He was less than 2lb when he was born, but since then has been greatly improving and now weighs 6lb 4 oz.
As for Sharista, doctors are still not certain of her prognosis, but she has done far better than they ever expected when she was admitted last December.
Her mum said: "We never gave up. She's fought this hard."
