The father of a baby B.C. boy who suffered head injuries after being hurled from his mother's car in Washington State is calling the infant's quick recovery a "miracle."

Baby Mohammed Khalid was airlifted to hospital with serious injuries Thursday after his mother's Honda SUV rolled over on the I-5 near Marysville around 11 a.m. Although he was ejected out onto the highway, authorities say the child could be released from hospital as soon as Saturday.

Father Nawaz Khalid travelled to Seattle from Surrey to visit Mohammed, and said everyone is lucky to be alive.

"I saw the car after, in the towing yard, and what the car looks like, it's a miracle," he told CTV News.

The infant's 27-year-old mother, Hira Khalid, told police she veered onto the right-hand shoulder then over-corrected to the left, losing control of the vehicle. She and her six and seven-year-old daughters suffered minor injuries in the crash.

Investigators believe the infant was not properly secured in his seat at the time and that the seat, which also flew onto the road, was not properly secured in the vehicle.

Nawaz Khalid says he has spoken to his wife since the crash, and she is certain Mohammed was buckled up properly.

"All she knows is the baby was crying before and his two sisters were sitting around him on each side and they are trying to calm him down and rocking him. They don't know if they touched it or opened the buckle or whatever happened," he said.

Trooper Keith Leary told ctvbc.ca the boy appears to be recovering quickly and is expected to be released from the Harborview Medical Center in Seattle over the weekend.

"I spoke to a charge nurse who said he's doing remarkably well. They didn't go into diagnosing injuries, but it's sounding positive," Leary said.

Leary said the whole family seemed to be doing better on Friday.

"The daughters are doing well, the mother's doing well. Her husband was up all night but he's getting some rest," he said.

No criminal charges are being pursued in the crash, Leary said, but the mother is being cited with "improper lane travel and car seat seatbelt violations."

Each citation carries a penalty of $124.

Police say drugs and alcohol were not factors in the crash.
