A Hamilton, Ont. mother is facing attempted murder charges after she tried to stab her eight-month-old baby girl, police say.

Emergency officials were called to an apartment building on Sandford Avenue North late Tuesday morning after receiving a 911 call from Children's Aid Workers who witnessed the alleged attempting stabbing.

"They found a child in distress; the child appeared to be suffering from stab wounds," Sgt. Michael Webber told reporters.

The toddler was rushed to hospital in serious condition, but police later said she suffered only superficial wounds.

Police said the infant is doing well, but will be kept overnight as a precautionary measure.

Another child in the household was taken into the care of the Children's Aid Society.

A 28-year-old mother was arrested and charged at the scene. Her name is not being released because the case involves the CAS.

News of the attack shocked neighbours.

"I heard about the baby and it's ignorant," said one man. "I don't know what else to say. It's just disgusting."

Residents were relieved to hear the toddler was not seriously hurt in the incident.

The Hamilton police child abuse unit is continuing to investigate.

Webber said the involvement of the aid workers is also being reviewed.
