9 Interesting Facts About Fall Babies

October 25, 2016


So you’re having a fall baby. Congratulations! Did you know that autumn babies are unique in a lot of ways? Neither did I. Consequently, today, I’m sharing nine interesting facts about fall babies, to get you excited. (And also because I kind of geek out on random facts.) So put on your favorite sweater, grab a cup of hot chocolate (or a pumpkin spice latte, I’m not going to judge you) and enjoy!

Fall babies weigh less

According to the Proceedings of the National Academy of Science, babies gestate an average of a week less than their non-fall/winter peers, and weigh less too. So maybe knowing that will make your lady parts a little less nervous to give birth?

They tend to be taller.

If you’re hoping your kid’s the next LeBron, you may be in luck. According to a Bristol study in the United Kingdom, late summer/early fall babies are slightly taller on average than children born in the winter or spring. This could be because the final stretch of these pregnancies happen in the summer, when the mom is more exposed to the sun. Her body then produces more vitamin D, which may aid in the skeletal growth of her child.

They have stronger bones.

The same study mentioned above also found that late summer/early fall babies also have thicker bones (by 12.75 square centimeters, if you like numbers). I’m not saying you’re birthing a superhero… but I don’t know, anything’s possible. Just ask Luke Cage.  

They are great athletes.

Research shows that autumn babies have an edge when it comes to athletics. September and November babies are the most fit, with October coming in second. This may be due to the increase in vitamin D, or the fact that older kids may have an edge over their younger counterparts who are in the same grade, but either way, it’s science.  

Autumn babies live longer.

Depending on the study, anywhere from 160 to 219 days longer. And, according to another study by the University of Chicago, the most centenarians were born between September and November.

They may be more prone to asthma.

According to a Vanderbilt University study, babies who tend to be around four months old during the height of the cold and flu season (which is when they no longer can depend on their mothers’ immune systems for protection) tend to have higher rates of asthma than their summer-born counterparts.  

Fall babies tend to have more food allergies.

A Finnish study found that babies born in October and November were more likely to develop food allergies, particularly to eggs and milk. The theory is that this may be due to the high pollen counts that occur in spring, which coincide with important immune system development that is happening in utero at the same time.

They excel academically.

So you may have a super athlete and a super mathalete all in one child. A study of 48,000 British kids by the Institute for Fiscal Studies found that children born in September are 20% more likely to get into elite schools than those born in August. Could this be because of the September 1 cutoff for school enrollment? Maybe. But I’d still probably start planning for early retirement now. 😉

More babies are born in September than any other month of the year.

If you take a look at this cool graph, you’ll see a ranking of US births from 1973 to 1999. It shows that more babies were born in September, with September 16 being the most common birthday. This trend seems to be holding, as the winter months (when these babies are conceived) tend to encourage a little more “coziness.”

True oh the height factor my friends and I that are born in November are 5’11 to 6’5 but I was 10.1 and I’m 14 and I’m almost 6’2


I don’t think it has anything to do with when babies are born… Fall babies weigh less?? My girls weighed 8.0 and 8.3 born in June and Feb… My boy weighed 9.7 and he was November lol
