Weeks 1-4: Conception and Implantation
The journey of baby development starts with conception. The sperm fertilizes the egg, and the resulting zygote begins to divide into multiple cells as it travels down the fallopian tube towards the uterus. Once it reaches the uterus, the zygote implants itself into the uterine wall, where it will continue to grow and develop over the coming months.
Weeks 5-8: Embryo Development
During weeks 5-8, the developing baby is called an embryo. At this stage, the embryo’s organs and body parts begin to form. The heart starts beating, and the facial features, arms, and legs begin to take shape. By the end of week 8, the embryo is about an inch long and is starting to look more like a human.
Weeks 9-12: Fetal Development
During weeks 9-12, the developing baby is called a fetus. The fetus grows rapidly during this time, and its organs continue to develop and mature. The fingers and toes separate, and the fetus starts moving and kicking. By the end of week 12, the fetus is about 3 inches long and weighs about half an ounce.
Weeks 13-16: Growth and Movement
During weeks 13-16, the fetus continues to grow and develop. The skin becomes more opaque, and the bones begin to harden. The fetus starts to move more, and the mother can feel the baby kicking and moving around. By the end of week 16, the fetus is about 6 inches long and weighs about 4 ounces.
Weeks 17-20: Sensory Development
During weeks 17-20, the fetus’s senses start to develop. The eyes can detect light, and the ears can detect sounds. The fetus can also taste and swallow amniotic fluid. The mother may start to feel the baby hiccupping, which is a sign that the baby’s diaphragm is developing. By the end of week 20, the fetus is about 10 inches long and weighs about 10 ounces.
Weeks 21-24: Viability
During weeks 21-24, the fetus reaches viability, which means that it has a chance of surviving outside of the womb if born prematurely. The fetus’s lungs continue to develop, and it starts to practice breathing by inhaling and exhaling amniotic fluid. The fetus also starts to develop more hair and nails. By the end of week 24, the fetus is about 12 inches long and weighs about 1.5 pounds.
Weeks 25-28: Brain Development
During weeks 25-28, the fetus’s brain continues to develop rapidly. The fetus can now blink its eyes and can respond to sounds and light. The lungs continue to mature, and the fetus starts to gain more weight. By the end of week 28, the fetus is about 14 inches long and weighs about 2.5 pounds.
Weeks 29-32: Growth and Development
During weeks 29-32, the fetus continues to grow and develop. The skin becomes less wrinkled as fat deposits build up, and the fetus starts to look more like a newborn baby. The fetus’s immune system also starts to develop, and it starts to produce antibodies. By the end of week 32, the fetus is about 16 inches long and weighs about 4 pounds.
Weeks 33-36: Final Preparations
During weeks 33-36, the fetus is making its final preparations for birth. The fetus starts to position itself head-down in the mother’s pelvis, which is the optimal position for birth. The fetus’s bones continue to harden, and the lungs are almost fully developed. By the end of week 36, the fetus is about 18 inches long and weighs about 5.5 pounds.
Weeks 37-40: Full-Term
During weeks 37-40, the fetus is considered full-term, which means it is ready to be born. The fetus continues to gain weight and may grow up to a half-pound per week in the final weeks of pregnancy. The fetus’s skin becomes smooth, and the vernix, a waxy substance that protects the skin, begins to disappear. By the end of week 40, the fetus is about 20 inches long and weighs about 7.5 pounds.
