Pregnancy is a beautiful journey that every woman experiences in her life. From the moment of conception, the body starts to change and develop to accommodate the growing fetus. It is fascinating to see how a tiny cell transforms into a fully formed baby over the course of nine months. In this article, we will take a closer look at how a baby develops during pregnancy.

First Trimester (Week 1 – Week 12)
During the first trimester, the fertilized egg travels down the fallopian tube and implants itself in the lining of the uterus. The baby’s development starts right from the moment of conception. By the end of the first week, the fertilized egg has divided into multiple cells, forming a blastocyst. This blastocyst then implants itself in the uterus.
By the end of the fourth week, the baby’s heart has started to beat, and the neural tube, which will later become the spinal cord and brain, has formed. The baby’s organs, including the liver, kidneys, and digestive system, start to develop during this trimester. By the end of the twelfth week, the baby’s facial features, limbs, and fingers have formed, and the baby is now around 2.5 inches long.
During the second trimester, the baby’s development continues at a rapid pace. The baby is now able to move and kick, and the mother can feel these movements. The baby’s skin starts to become covered with a fine hair called lanugo, which protects the skin from the amniotic fluid. The baby’s eyes, ears, and nose start to take shape, and the baby can now see and hear.
By the end of the second trimester, the baby’s lungs have developed enough to allow it to breathe air, although the baby would still need medical support if born prematurely. The baby is now around 14 inches long and weighs around 2 pounds. The baby’s brain continues to develop rapidly, and the baby can now dream.
Third Trimester (Week 29 – Week 40)
During the third trimester, the baby’s development focuses on gaining weight and preparing for life outside the womb. The baby’s brain continues to develop rapidly, and the baby can now recognize voices and sounds. The baby’s bones start to harden, and the baby’s immune system starts to develop.
By the end of the third trimester, the baby is fully formed and ready to be born. The baby is now around 20 inches long and weighs around 7 pounds. The baby’s lungs are now fully developed, and the baby can breathe air independently. The baby’s digestive system is also fully developed, and the baby is ready to start feeding.
