Input: The New England Journal of Medicine recently published a study suggesting that parents should wait 18 to 23 months after a full-term birth before conceiving again. Interestingly enough, the average age gap between siblings in America is about two and a half years -- which means we must be following this advice! I personally have two sisters, one 6 years older and the other 11 years older, and we get along famously. You have to worry about competition between siblings when the age gap is too small; but with families with wide gaps in age between the siblings, you have to worry that they'll be raised almost like one "only child" after another. Best,
'k.
Output:
What's the best age gap between siblings?
