A 42-year-old Sydney mother has been charged with murdering her five-year-old son and attempting to murder her two other children, aged one and three, after allegedly stabbing them inside the family car in the Blue Mountains on Sunday.

A woman already facing court over the death of a five year old child in an alleged stabbing attack in the Blue Mountains will now face a second murder charge following the death of a second child, aged just one, in hospital.

Emergency services were called to reports of a vehicle found on Waratah Road in Valley Heights, where three children and a woman were allegedly discovered inside with stab wounds.

Blue Mountains police officers at the scene were told several members of the public performed first aid on the woman, 42, and three children whilst contacting Triple Zero.
