6 Reasons December Babies Are Special

We have no control over our birth month. But of the twelve months, if you were born in December, science is on your side. Whether you’re supposed to give birth to a December baby or you are a December baby, we’ve got some good news. December babies are extra special!

Many parents have anxiety over giving birth to December babies – for a number of reasons. Some don’t want their newborn’s special day to be overshadowed for the rest of their life; others worry about bullies picking on them because they’re the youngest in the class. Hopefully what you’re about to read helps put you at ease… Because research suggests that being born in December can give you quite an advantage in life.

1) Did we mention they’re super special?

While it doesn’t apply to every single December baby, those who are born on December 24 or 25 have two of the rarest birthdays!

2) They Are More Likely to Live to 100

Speaking of birthdays, December-born babies are likely to live the longest, according to the Journal of Aging Research. In fact, upon reviewing their findings, researchers found that they have a “significantly higher risk of surviving up to age 105-plus compared to the June-born.”

In June 2015, Columbia University Department of Medicine researchers published an article about how birth month affects lifetime disease risk. During the study, they analyzed records of 1.75 million patients between 1900 and 2000 as well as 1,668 disease and birth months and other factors (e.g., exercise and diet). (4)

Researchers emphasized that babies born in June, August, January, and December didn’t provide a significant advantage or disadvantage when it came to contracting major diseases. However, other late months, “such as October and November, were associated with increased risk of disease.” (5) In comparison to others born late in the year, the study suggests that December babies may have more of a fighting chance against disease.

Compared to people born in winter, summer-born babies tend to be more moody. A study presented at the European College of Neuropsychopharmacology surveyed 366 university students about their temperaments. Not only were people born in winter more steady, but December babies threw even less temper tantrums. (6)

Believe it or not, being older doesn’t guarantee intelligence! Two groups of economists in 2006 and 2007 found that children who started school a year later had significantly lower IQ scores and performed more poorly than their younger counterparts. (7,8,9)
