Lethbridge police say a six-week-old girl remains in critical condition in the Alberta Children's Hospital in Calgary as investigators continue to look into the circumstances behind her injuries.
Police say they've received numerous messages of support in recent days for the infant.
Paramedics took her to hospital last Wednesday after officers found the baby in medical distress inside a Lethbridge residence.
"She is receiving the highest level of care and all her needs are currently being met by her caregivers," said a police statement on Monday. "Thank you to everyone who has reached out in support of the baby."
According to investigators, officers responded to a report of the baby being abused on Jan. 18.
Police found the child in medical distress, with both her parents in the home. An ambulance brought the girl to hospital.
Police said the child had suffered extensive injuries while being physically and sexually abused since the time of her birth.
The father is facing charges of aggravated assault, sexual assault, sexual interference and failing to provide the necessaries of life.
The mother is charged with a single count of failing to provide the necessaries of life.
The parents were not named to protect the identity of the child.
Lethbridge is about 200 kilometres south of Calgary.
