The First Trimester
The first trimester is the most crucial period of your baby’s development. During this time, your baby is going through rapid growth and changes. The first several weeks are when the major organs and body systems begin to form, such as the heart, lungs, and brain. By week 8, your baby is about the size of a raspberry, and all major organs are in place. At this point, your baby is referred to as a fetus.
By week 12, your baby is fully formed, and all the organs are functioning. It’s amazing how much can happen in just 12 weeks, isn’t it? At this point, your baby is about the size of a lime, and you can often hear the heartbeat with a doppler.
The Second Trimester
The second trimester is known as the “honeymoon” period of pregnancy because many women find that they feel their best during this time. During weeks 13-28, your baby will continue to grow and develop, but at a slower pace than during the first trimester. By week 16, your baby is about the size of an avocado, and you may start to feel the first flutters of movement. The baby’s skin is still translucent at this point, but it will start to become more opaque over the next few weeks.
By week 20, your baby is about the size of a banana, and you will be able to find out the sex of your baby if you choose to do so. Your baby’s hair, eyelashes, and eyebrows will start to grow, and the baby will start to develop a sleep/wake cycle. By week 24, your baby is about the size of an ear of corn, and their lungs are developing rapidly in preparation for breathing.
The Third Trimester
The third trimester is the final stretch of pregnancy, and it’s when your baby will do the most growing. By week 28, your baby is about the size of a large eggplant, and their eyes can now open and close. By week 32, your baby is about the size of a squash, and their bones are fully formed but still soft and pliable.
By week 36, your baby is about the size of a honeydew melon, and their organs are fully developed and functioning. From this point on, your baby will mostly be putting on weight and preparing for birth. By week 40, your baby is fully developed and ready to make their grand entrance into the world!
