When you’re pregnant with your first baby, there are so many things to be excited about. From getting the nursery ready to buying cute outfits, there’s always something to look forward to.
However, one thing you may not be so thrilled about is having a small baby. Most parents worry about either having a big or small baby, and some want to understand why their baby might be small.
A small baby is less than ideal for many, and the main concern is that it may signal health problems. However, there are a few reasons why your baby might be on the smaller side, and in most cases, it’s nothing to worry about. Understanding the cause of your baby’s small size can help you better prepare and give you the opportunity to consult with your doctor.
It’s important to remember that not every small baby is unhealthy. So, don’t be overly concerned if your baby is a bit on the smaller side. There are several reasons this might happen, and it’s good to be informed. From maternal health to how the baby is positioned, many factors can contribute to a smaller baby. Let’s take a look at the seven main reasons.
7 Reasons Your Baby Could Be Born Small In Size
1. Genetics and Family History
One of the most common reasons for a small baby is genetics. If you or your partner were small as newborns, your baby is more likely to be small as well. If small babies run in the family, there’s a possibility your baby will follow that pattern.
If the baby’s small size is simply due to genetics, there’s usually no need for concern. Some women naturally carry smaller babies and experience no adverse effects.
Key Takeaway:
Small baby size can be genetic. If it runs in the family, your baby is likely to be small too.

2. Placenta Not Working Properly
If the placenta isn’t working properly, your baby may be on the smaller side. The placenta is responsible for taking oxygen and nutrients from the mother’s blood and delivering them to the baby. When it doesn’t function well, the baby may not receive enough nutrients or oxygen.
Placental inefficiency can occur due to conditions like high blood pressure, which restrict blood flow to the placenta. As a result, the baby may not grow as expected, leading to a smaller birth size.
Key Takeaway:
If the placenta isn’t functioning properly, the baby may not get enough oxygen and nutrients, leading to slower growth and a smaller size.
3. Mother’s Health Condition
The mother’s health condition also plays a role in the size of the baby. Certain conditions, such as high blood pressure or diabetes, can lead to a small baby. Maintaining good health is important for the health of both mother and baby.
For example, conditions like preeclampsia, kidney disease, gestational diabetes, or other high-risk pregnancies can decrease the oxygen and nutrient supply to the baby, leading to growth restrictions.
Key Takeaway:
If the mother has health conditions that restrict oxygen or nutrients to the baby, it can impact the baby’s growth.

4. Multiple Pregnancy (Twins, Triplets, Etc.)
If you’re expecting multiples, like twins or triplets, your babies are more likely to be smaller. This is because each baby has less space to grow and develop. Additionally, they share the available nutrients and oxygen, so they receive less than a single baby would.
Multiple pregnancies often lead to preterm births, which can also result in smaller babies. If you’re pregnant with more than one baby, there’s a good chance that each one will be smaller in size.
Key Takeaway:
In multiple pregnancies, it’s common for each baby to be smaller than average.
5. Poor Diet or Nutrition During Pregnancy
A poor diet or lack of proper nutrition during pregnancy can lead to a small baby. The baby depends on the mother’s diet for nutrients and energy, so it’s important for the mother to maintain a healthy diet. If the mother is not eating well, it can affect the baby’s growth.
Make sure you’re getting enough iron, protein, calcium, and folic acid during pregnancy. Poor nutrition can also lead to other complications, such as preterm labor.
Key Takeaway:
If the mother is not eating a proper diet, it can result in a smaller baby.

6. Smoking and Drug Use During Pregnancy
Smoking and drug use during pregnancy are both known to lead to smaller babies. The toxins from these substances are passed to the baby through the placenta, which can damage the baby’s development.
Smoking has also been linked to preterm birth, which often results in a smaller baby. Drugs and alcohol can also cause withdrawal symptoms in the baby at birth.
Key Takeaway:
Avoiding smoking and drug use during pregnancy is crucial to ensure your baby is not born smaller than expected.

7. Premature Birth
If a baby is born prematurely (before 37 weeks gestation), it is more likely to be smaller than a full-term baby. Premature babies are often small because they haven’t had enough time in the womb to fully develop. There are many factors that can cause premature birth, such as stress, multiple pregnancies, and health conditions.
While premature babies tend to be smaller, they can still develop normally after birth. If born early but at a healthy weight (over 5 pounds), they can still grow and thrive.
Key Takeaway:
Premature birth often leads to a smaller baby because the baby didn’t have enough time in the womb to fully grow.
Conclusion
It’s common to feel concerned when you find out that your baby is on the smaller side. There are many reasons why this could be, and it’s important to understand the cause. In most cases, a small baby is not a problem and is simply the result of genetics or other factors beyond your control.
It helps to talk with your doctor to understand why your baby is small, so you can prepare accordingly. Regular check-ups, maintaining a healthy diet, and avoiding smoking and drugs are key to ensuring your baby is growing as expected. By understanding the reasons behind a smaller-than-average baby, you can focus on the steps that are best for your baby’s health and development.
