5 Interesting Facts About Babies Born in September

September is the start of a lot of change. First, we see it in nature with the changing color of leaves as we exit summer fun and experience cooler temperatures. It’s also when kids head back to school, and birds begin their migration to warmer climates. It’s also one of the more comfortable months to be pregnant.

It’s also a month of change for parents-to-be who are expecting a new baby during the month. However, according to science, there are some interesting perks for those who have a September birthday.

If you’re expecting a little one in September, here are some fun facts about babies born this month.

Traditional school isn’t a good fit for everyone since there are many different ways to learn. However, babies born in September tend to do well in school, according to science.

A report from the National Bureau of Economic Research looked at the grades of students between the ages of 6 and 15 and found that September-born kids had higher scores on average than their peers did.

While this isn’t specific to September-born babies, a study did find that autumn-born babies do better in sports as they age.

A research team in Essex looked at data from 8,550 boys and girls between the ages of 10 and 26 and found that babies with autumn birthdays just did a lot better in sports — especially when compared to late spring and summer-born babies.

Some people are lucky enough to live a long life, and kids born in September are more likely to reach that milestone, according to research. The scientists of the study found that kids born between September and November are “more likely to live to 100 than those born in other months of the year.”

Though many studies have pointed to the same result, it’s unclear why. The leading theory seems to be that early exposure to viruses and germs sets the body’s immune system up to fight them off more efficiently, leading to longer life spans.

There are 365 days a year, but each of those days isn’t equal in terms of how many people are born within 24 hours. According to science, looking at actual birth data spanning 20 years, mid-September is the most popular time of the year for babies to be born.

More specifically, September 9 is the most popular day for babies born in the US, followed by September 19.

Science has shown that the time of year a baby is born can come with some health conditions that might be more likely to develop based on the data collected. For example, for babies born in the fall, research has shown that they are less likely to experience depression or bipolar disorder than those born in other months.

However, September-born kids are more likely to be cranky or irritable.
