The moment a woman conceives, a new life begins. The fertilized egg, also known as a zygote, starts to divide and grow rapidly. It is an exciting time for expectant parents, but many may wonder when exactly does a baby start developing after conception?

Week 1-2: The Beginning of Life

The first two weeks of pregnancy are often considered the preconception period. During this time, the egg is fertilized by sperm and travels down the fallopian tube to the uterus, where it implants in the uterine lining. This is the start of pregnancy and the beginning of fetal development.

Week 3-4: Formation of the Embryo

During the third and fourth weeks of pregnancy, the zygote continues to divide and undergoes a process called gastrulation. This is when the cells start to differentiate and form three distinct layers that will eventually become the organs and tissues of the body. The neural tube, which will become the brain and spinal cord, also begins to form during this time.

Week 5-8: Major Developmental Changes

Between weeks five and eight, major developmental changes occur. The embryo now resembles a tiny human, and the heart starts to beat. The limbs, fingers, and toes begin to form, and the eyes and ears start to take shape. The neural tube also closes, protecting the growing brain and spinal cord.

Between weeks thirteen and sixteen, the fetus becomes more active, moving around and even sucking its thumb. The sense of hearing develops, and the fetus can hear the mother’s voice and other sounds. The eyes can now blink, and the skin becomes more opaque, hiding the internal organs.

Week 17-20: Quickening and Hair Growth

During weeks seventeen through twenty, the mother may feel the first movements of the fetus, known as quickening. The fetus also starts to grow hair, and the skin becomes covered in a waxy substance called vernix caseosa. The bones begin to harden, and the digestive system starts to work.

Week 21-24: Brain Development

Between weeks twenty-one and twenty-four, the brain continues to develop, and the fetus can now dream. The lungs also start to develop, and the fetus practices breathing. The skin becomes less transparent, and the fetus gains more weight.

Week 25-28: Survival Outside the Womb

During weeks twenty-five through twenty-eight, the fetus becomes more active and responsive to sounds and light. The eyes can now open and close, and the lungs continue to develop. The fetus also has a better chance of survival outside the womb if born prematurely.

Week 37-40: Ready for Birth

In conclusion, a baby starts developing immediately after conception and goes through many changes and stages of development before being born. From the moment of conception, the zygote starts to divide and grow rapidly, eventually forming a baby ready for birth. It is a remarkable journey that results in the miracle of life.
