FAQ
Can maternity benefit and salary be received together?
No double-dipping. The fund pays benefit = employer average wage ÷30 × leave days; if below your salary, the employer tops up the difference.
How do I read the baby vaccine schedule?
National immunization vaccines are free and month-age critical (HepB 0-1-6 months, IPV at 2/3/4 months + booster at 4, etc.). Generate the full dated schedule from the birth date.
When should education savings start?
As early as possible — compounding is about time. Set the age-18 target and back-solve the monthly deposit; starting at birth needs roughly one-third of the last-minute amount.
