10 Fun Facts About Twins For Expectant Moms

The twin birth rate is on the up and up worldwide and the fascination with all thing twin keeps on growing. Every child, I dare say, would love to have a twin and everyone seems to have a “how the twins fooled me” type story to tell. Identical or not, twins have always captured our imagination and managed to mesmerize, so much so, that you just wanna find out more.

First-time moms of twins will eagerly long to find out all there is to know, and here are some fun facts that will make you smile and wonder with amazement:

  1. Genetics are More Powerful than Environmental Factors: Even if twins are separated at birth and raised by different sets of parents they often display similar characters. Anecdotal evidence exists that such twins often make similar life choices, display matching likes and dislikes and often share strong personality traits.
  2. Twins Don’t Have to Be the Same Race: If both parents are mixed race, couples may very well have two twins of different skin color. This is because both sperm and egg will always contain genes for both races and there is an endless number of possible combinations that will ultimately determine the twin’s individual race.
  3. Secret Language: Research suggests that up to 40% of twins develop their own secret language and that all twins teach each other words, some of them made up of course.
  4. Moms of Twins Live Longer: Recently conducted studies suggest that moms of twins live longer.
  5. Drink Lots of Milk if You are Hoping for Twins: Mothers who drink lots of milk and eat dairy products such as cheese and yogurt are more likely to conceive twins. Vegans, however, are five times less likely to have twins.
  6. Close Bond: Twins are thought to engage in some form of interaction in the womb as early as at fourteen weeks. Many twins sleeping side by side, find themselves holding hands and snuggling up in their sleep, presumably in an instinctive attempt to relive the closeness experienced in the womb.
  7. Mirror Images: 25% of identical twins are said to be mirror images of each other. One may have a birthmark on his left shoulder while the other has it on the mirroring right shoulder.
  8. Breast Temperature: If a woman breastfeeds twins simultaneously, each breast will automatically adjust its temperature to suit each baby.
  9. Fingerprints: Though identical twins closely share their looks, their fingerprints are different.
  10. Polar Bears Mostly Have Twin Births: While the human twin rate is relatively low, polar bears mostly give birth to twins.

Having twins is truly amazing and being a twin even more so and it is hard to imagine a bond closer than that of two little babies sharing the small space of mom’s womb, growing and developing side by side.

    Wow interesting facts about twins! My cousin are twins and growing up I used to always confuse the two.

  3. Chris Lewis says

    Great things to consider. I know some twins and definitely can see these factors, though I may not have thought of them initially.

  4. Tamara says

    #2 and #3 blow my mind! The secret language is amazing. Twins runs in my family but I haven’t had them. I’d love to have twins, though.

  5. candy says

    I have noticed just around our community the number of twin births are high. Never knew many of these facts and they are extremely interesting. Will have to share with the twin moms I know.

  6. valmg @ Mom Knows It All says

    I have heard about the bond and the special language twins can share before. I have known one set that was very close, but another that wasn’t particularly close.

  7. Paula Schuck says

    Oh my goodness I actually didn’t know several of these. We have twins in our family and I thought I knew a lot about the topic. I didn’t know the information about polar bears at all. I also didn’t know that twins could be different races…hat is wild!!

  8. Jeanette says

    I never knew about the whole breast temperature thing! That is really interesting! I’ve never had twins but my cousin has had twins. I’m going to ask her about this

  9. Karen Clough says

    Oh wow there’s loads I never knew in here! I always thought how wonderful it would be to have twins, but after having just the one toddler, she’s a handful on her own haha!

  10. lisa says

    This is a lot of neat information about twins! I have a few friends that have twins, but I never knew most of this!

  11. Melanie says

    If moms of twins live longer, I wonder how long moms of triplets live? I’m a triplet mom, so I hope that is a good thing! Haha!

  12. Pam W says

    I had no idea that vegans are less likely to give birth to twins. I wonder why that is?

  13. Jenn @ EngineerMommy says

    This is a cool list. I never knew that about breast feeding twins. I breast fed my kids for two years. It’s amazing how the body adjusts to the kid’s needs.

  14. Stephanie Pass says

    This is so fascinating! With my dairy habits, I’m surprised I’m not 100x likely to have twins, lol. Your girls are adorable!

  15. Dawn McAlexander says

    There are a lot of these facts that I was not aware of at all. I feel a little more enlightened now about twins. Thanks!

  16. lisalisa says

    Very interesting facts indeed! Your twins are just adorable, I bet they keep you busy!

  17. Kita Bryant says

    Oh how interesting! Twins must be very exciting, and exhausting.

  18. Twins genes don’t run in my family but I wanted to have twins. I know it’ll be exhausting but I can imagine how fun it would be.

  19. Gina says

    I love the facts you bring up here. I have twin boys. FRATERNAL boys. Essentially, I had two completely separate pregnancies occur at the same time. They are very different than you talk about here. One has literally nothing to do with the other. There is no twin language or bonding going on, although they are each other’s best friend. They are fun to be with, but because they each march to their own drum, it’s not often “fun.” It seems I’m usually running in opposite directions. One says “black” the other says “white”. One likes sweet food, the other likes salty food. One likes veggies, the other hates it. One likes being outside, the other doesn’t. I find it interesting that many women wish they could have twins. Be aware that it’s WORK WORK WORK. Everything is double, from sleep schedules to food to diapers to school supplies to soccer registrations to health insurance to tuitions. Now…don’t get me wrong. I LOOOOOVE my boys. I super super love them!!!! I couldn’t stand one day without them. But it can be quite challenging. My hair has quickly gone gray. I sometimes think that moms with identical twins got the easy way to go, but I know you have it tough sometimes too. That’s motherhood. It’s true for us all. And I wouldn’t trade it for the whole wide world.

    Twins have such an amazing bond, I did not know a lot of this. I bet that having twins must be such an amazing and fun experience.
