The Stages of Baby Development
Congratulations, Mama! You’re pregnant and soon to be holding your little bundle of joy in your arms. But have you ever wondered what happens during those 9 months of pregnancy? Well, wonder no more! Let’s take a closer look at the stages of baby development, week by week.
Weeks 1-4
The first 4 weeks of pregnancy are considered the first trimester. During this time, the fertilized egg travels down the fallopian tube and implants itself in the uterus. The zygote, which is what the fertilized egg is called at this stage, begins to divide and grow rapidly. By the end of the fourth week, the embryo is about the size of a poppy seed.
Weeks 5-8
During weeks 5-8, your baby is now officially called an embryo. At this stage, the embryo’s heart begins to beat, and the baby’s brain and spinal cord start to form. The embryo also develops arm and leg buds, and its facial features begin to take shape. By the end of the eighth week, the embryo is about the size of a raspberry.
Weeks 9-12
During weeks 9-12, the embryo is now considered a fetus. The fetus begins to move around, although you won’t be able to feel it just yet. The baby’s organs and muscles continue to develop, and its sex organs begin to form. By the end of the twelfth week, the fetus is about the size of a lime.
Weeks 13-16
During weeks 13-16, your baby’s bones begin to harden, and its skin becomes less transparent. The fetus also begins to develop fingerprints, and its eyes move from the side of its head to the front. By the end of the sixteenth week, the fetus is about the size of an avocado.
Weeks 17-20
During weeks 17-20, your baby’s senses begin to develop. The fetus can now hear and may even startle at loud noises. It also begins to develop hair, and its taste buds start to form. By the end of the twentieth week, the fetus is about the size of a banana.
Weeks 21-24
During weeks 21-24, your baby’s lungs begin to develop. The fetus also begins to gain weight rapidly, and its skin becomes less wrinkled. By the end of the twenty-fourth week, the fetus is about the size of an ear of corn.
Weeks 25-28
During weeks 25-28, your baby’s brain continues to develop rapidly. The fetus also begins to develop more body fat, which will help regulate its body temperature after birth. By the end of the twenty-eighth week, the fetus is about the size of a large eggplant.
Weeks 29-32
During weeks 29-32, your baby’s muscles and lungs continue to mature. The fetus may also begin to settle into a head-down position in preparation for birth. By the end of the thirty-second week, the fetus is about the size of a butternut squash.
Weeks 33-36
During weeks 33-36, your baby’s bones are now fully formed, but still soft and pliable. The fetus also continues to gain weight and may move less frequently because it’s getting crowded in there! By the end of the thirty-sixth week, the fetus is about the size of a honeydew melon.
Weeks 37-40
During weeks 37-40, your baby is considered full-term and ready for birth. The fetus continues to gain weight and its organs continue to mature. The baby’s head may also engage in the pelvis, which is a sign that labor may be approaching. By the end of the fortieth week, the fetus is about the size of a small pumpkin.
