Size of Your Baby Throughout Pregnancy

Feeling your baby grow throughout your pregnancy is one of the weirdest feelings in the world. It most likely makes you anxious to find out what your baby is going to look like or how big they will be. While ultrasounds are the only way to see your baby until birth, most babies are around the same size throughout pregnancy. Here is a fun way to follow along with the size of your baby throughout pregnancy. These fun comparisons will help you get an idea of how big your baby is inside your belly.

Week 4

This is the week your baby begins to form and develop. Your baby is almost microscopic during this week and smaller than a poppyseed. Many women may not even know they are pregnant yet. However, this is the week that many women can find out they are pregnant. If you discover you are pregnant this week you should begin taking prenatal vitamins for a healthy pregnancy. Although, many women who plan on getting pregnant begin taking them sooner.

First Trimester

By the end of the first trimester, your baby has grown a ton. They have grown from the size of a poppyseed to the size of a lemon. This is one of the most dangerous times for your baby since it is a time of such vital development. Pregnant women should be especially careful during this time and take care of themselves and their babies. Here are some activities to consider avoiding. After 10 weeks is the time that most women decide to announce their pregnancy once the risk of miscarriage drops compared to previous weeks. By the end of the first trimester, arms and legs have formed along with the baby’s vital organs like lungs, kidneys, and the heart.

Second Trimester

The second trimester is when a baby bump first begins to form. This is most often the most enjoyable trimester for pregnant women. Most morning sickness is gone, and you can finally start to see and feel your baby growing inside you. The baby also starts to move during the second trimester. Another one of the most exciting things the baby develops during this time is hearing. Your baby can now hear you and the world around them. By the end of this trimester, the baby is the size of a head of lettuce. Chances of going into labor during this trimester are very low but possible. The average baby at the end of the second trimester is 2.3 pounds.

Third Trimester

By the third trimester, you are most likely getting a little anxious about the arrival of your little one. By the end of the third trimester, your baby will be born and will have grown to the size of a watermelon or smaller. The average size of a full-term baby is 8.3 pounds. However, most women do not give birth on their due date and can go into labor at any time during this trimester and still have a healthy baby. Keeping track of the size of your baby throughout pregnancy is one of the most exciting things to do. It can help your baby feel a little more real since you cannot see them.
