Shannon Deschamps, who is 36, of Hobbema, was supposed to begin a five-day trial Monday on a charge of aggravated assault in Red Deer court.
But she didn't show up.
A warrant has been issued for her arrest.
Her lawyer also asked to be taken off the record.
In November 2009, police laid charges after a newborn baby was brought to Red Deer Regional Hospital with what officials deemed suspicious but non-life threatening injuries.
