DRUMMONDVILLE, Que. - Sonia Blanchette, 33, charged in the drowning deaths of her three young children, has been declared fit to stand trial after a month-long psychiatric evaluation.

She faces three charges of first-degree murder, but she has not yet registered a plea.

Blanchette is scheduled back in court on March 28. The report on her evaluation has been sealed and won't be available to the public before her trial.

Blanchette is accused of drowning her three kids -- Anais, 2, Loic, 4, and Lorelie, 5 -- in her Drummondville apartment on Dec. 2. She didn't have custody of the children at the time. They were under the care of their father.

According to a family friend, the children rarely visited their mother, and when they did, the meetings were supervised. Their maternal grandmother would have been supervising the day they died, but was absent when it happened.

Drummondville is located about 100 km northeast of Montreal.
