It is alleged that two days earlier she had left the children, aged four and six, at home by themselves.
Police were called to the premises and entered the house through an unlocked door.
The woman, who is heavily pregnant, has not yet entered pleas to two charges of engaging in conduct that may have resulted in harm to the children.
Today lawyer Edward Fitzpatrick told the Perth Magistrates Court the woman was “not happy” with the advice he had given her and so he had “departed” from the case.
Mr Fitzpatrick also said the two children remained in the care of the authorities.
The woman, who was assisted in court by a Mandarin interpreter, was released on bail until her next court appearance.
