Pregnancy is a wonderful and miraculous journey. A lot happens in the nine months leading up to the birth of a baby. The development of a baby in the uterus is a fascinating process. This article will provide you with an in-depth guide on how a baby develops in the uterus.
The first trimester of pregnancy is a crucial time for the development of a baby. During this phase, the fertilized egg will implant itself into the uterus, and the placenta will begin to form. The placenta is a vital organ that nourishes the developing baby. At this stage, the baby is called an embryo, and all of its organs and body parts will begin to develop.
At week four, the embryo is about the size of a poppy seed. The heart begins to form, and the neural tube, which will later become the spinal cord and brain, starts to develop.
By week eight, the embryo is about the size of a raspberry. The major organs, such as the liver, kidneys, and lungs, begin to form, and the embryo starts to resemble a tiny human. The heart is fully formed and starts to beat.

By week 16, the fetus is about the size of an avocado. The fetus’s muscles begin to develop, and it can make facial expressions such as frowning and squinting. The fetus’s eyes can move, and it can sense light.
At week 20, the fetus is about the size of a banana. The fetus’s skin becomes less transparent, and it starts to produce meconium, which is the baby’s first bowel movement. The fetus’s taste buds develop, and it can taste the amniotic fluid.
By week 24, the fetus is about the size of an ear of corn. The fetus’s lungs begin to produce surfactant, which helps the lungs expand and contract. The fetus’s brain develops rapidly, and it can dream.
The third trimester is a time of preparation for birth. The fetus’s organs will continue to mature, and it will gain more weight and size.
By week 28, the fetus is about the size of an eggplant. The fetus’s eyes can open and close, and it can blink. The fetus’s immune system starts to develop, and it can now respond to sounds outside of the womb.
At week 32, the fetus is about the size of a squash. The fetus’s bones are fully formed, but they are still soft and pliable. The fetus’s skin becomes less wrinkled, and it starts to develop more fat.
By week 36, the fetus is about the size of a head of romaine lettuce. The fetus begins to move into the head-down position in preparation for birth. The fetus’s lungs are fully developed, and it can now breathe air.
