National Only Child Day – April 12, 2025

Not having siblings is your ticket to celebrate National Only Child Day on April 12. This holiday’s very special for those of us who don’t have a brother or sister and grew up as an individual child. National Only Child Day is especially apt because, in recent years, the number of only children has gradually risen, not just in the U.S. but over the globe as well. We think the date chosen for this event is perfect too because it comes right after Siblings Day on April 10, during which the sibling-less would have been left out.

History of National Only Child Day

Before population control was a necessity, people rarely had just one child. In fact, having more than one kid was considered prudent given that the death rate in infants was very high. So, if you look closely at historical records, only-child families were very uncommon all over the world in the early days.

Then, sometime during the 10th century, populations over the world began to exhibit a change. The average family size shrunk down to only one child. While pinpointing a particular cause for this decline in birth rates is near impossible, researchers and academicians theorize that it might have been a combination of various factors like the World Wars, the rise in living costs, and the higher standard of living. As children started living longer lives, and as the cost of raising a child went up drastically, the size of many families reduced to accommodate this new normal. The trend continued in more and more developed countries, until, country-by-country, nation-by-nation, and one-child homes became a common sight.

There is another key factor at play in the rise of ‘only children’ — the negative perception attached to these ‘onlies’ is slowly being debunked. The negative association started almost 100 years ago, with American psychologist Granville Stanley Hall, who declared that being an only child was “being an only child is a disease in itself.” He’d labeled only children as ‘indulgent’ and ‘spoiled.’ While his claims had zero evidence to back them up, they still became a worldwide phenomenon, to the extent that some people still believe the stereotype today.

A counter to these theories has been the world conducted in the late 1800s and early 1900s on only children, including various academic articles that counterchecked Hall’s — and others’ — claims that single children did not measure up to other kids. Whether because of finances, the environment, or another reason, more families are staying in a one-child home, and with it, establishing a new-ish, rich, family dynamic.
