Sonia Blanchette had her case put off today after appearing in court in Drummondville.
Blanchette was ordered last October to stand trial on three counts of first-degree murder in the deaths of her young children in December 2012.
The three children — Lorelie, 5, Loic, 4, and Anais, 2 — were found dead in their mother's apartment.
The coroner ruled the two youngest children drowned while the oldest child was killed by a combination of strangling and drowning.
Blanchette remains detained pending the outcome of her jury trial.
A court clerk says the case will resume April 9.
