Her bond was set Friday at $100,000.
Defense attorney Raymond De Leon says his client did not seek immediate help for 7-week-old Jayda De La Rosa because Navejar was poor and unsophisticated.
Navejar's 18-year-old boyfriend remains jailed and awaits trial on a charge of injury to a child causing serious bodily injury.
Jayda was found dead in September outside a fire station. She weighed just 4.5 pounds.
