It depends on your spouse. Discuss wt ur spouse n agree on a particular age u want ur children to be. As for me n my hubby, we agreed on five years interval. My first child will be 11yrs by Nov. Second was 6yrs in March. And my third child was six month in this month.

for the health and well-being of the mother, 18-23 months between the delivery of one child and conception of the next is the best.
