Waiting until mother is at least 18 years old before trying to have children improves maternal and child health.
If an additional child is desired, it is considered healthier for mother, as well as for the succeeding child,
to wait at least 2 years after previous birth before attempting to conceive (but not more than 5 years).After a miscarriage or abortion, it is healthier to wait at least 6 months.
