Week 1-2: Conception and Implantation
During week 1 and 2, your baby is not yet formed. Instead, this time is focused on conception and implantation. The sperm fertilizes the egg, forming a zygote. The zygote then travels through the fallopian tube to the uterus, where it implants itself in the wall. Once the implantation is complete, the fertilized egg begins to divide rapidly, laying the foundation for your baby’s growth.
Week 3-4: Embryo Development
During weeks 3 and 4, your baby’s embryo begins to take shape. The cells in the embryo differentiate into three layers: the ectoderm, endoderm, and mesoderm. These layers will eventually form all of your baby’s major organs and body parts. The heart also begins to form, and the neural tube – which will become the spine, brain, and nervous system – starts to develop.
Week 5-6: Organ Development
During weeks 5 and 6, your baby’s major organs continue to develop. The heart starts beating, and your baby’s arms and legs begin to form. The eyes, ears, nose, and mouth also begin to take shape. Additionally, the placenta begins to form, which will provide your baby with the nutrients and oxygen they need to grow.
Week 7-8: Baby Bump and Movement
During weeks 7 and 8, your baby’s growth really starts to take off. Your baby’s face becomes more defined, and their fingers and toes begin to separate. Your baby’s brain also continues to develop, and their nerves start to function. At this point, your baby’s movements may be visible on an ultrasound, and you may begin to feel your little one moving around in your belly.
Week 9-10: Growth Spurt
During weeks 9 and 10, your baby experiences a growth spurt. Their head makes up about half of their body size, and their facial features become more defined. Your baby’s fingers and toes are also fully formed, and their nails begin to grow. Additionally, your baby’s intestines begin to move into their proper position in the body.
Week 11-12: More Movement and Facial Expressions
During weeks 11 and 12, your baby becomes more active. They may start to suck their thumb, and their facial expressions become more complex. Your baby’s digestive system also starts to produce meconium, which is a dark, sticky substance that will eventually become your baby’s first bowel movement.
Week 13-14: Growing Hair and Teeth
During weeks 13 and 14, your baby’s hair begins to grow. They may also start to grow teeth, although these won’t be visible for several months. Additionally, your baby’s kidneys start to produce urine, which they will eventually excrete into the amniotic fluid.
Week 15-16: Limb Coordination and Hearing
During weeks 15 and 16, your baby’s limbs begin to coordinate more smoothly. They become more active, and may even start to kick and move around more. Your baby’s hearing also improves, and they may be able to hear your voice and other sounds from outside the womb.
Week 17-18: Developing Senses and Swallowing
During weeks 17 and 18, your baby’s senses continue to develop. They may start to develop a sense of taste, and their eyes begin to move back and forth. Additionally, your baby can now swallow amniotic fluid, which helps to develop their digestive system.
Week 19-20: Gender and Hair Growth
During weeks 19 and 20, your baby’s gender can often be determined through an ultrasound. Your baby also continues to grow hair, and their skin becomes less transparent. Additionally, your baby’s bone marrow begins to produce blood cells.
Week 21-22: Sleep Cycles and Eyebrows
During weeks 21 and 22, your baby’s sleep cycles become more regular. They may also start to develop eyebrows and eyelashes. Additionally, your baby’s sense of touch continues to develop, and they can now feel pressure and pain.
Week 23-24: Lung Development and Fingerprints
During weeks 23 and 24, your baby’s lungs start to produce surfactant, which helps them to breathe after birth. Your baby’s skin also becomes less wrinkled, and they start to develop unique fingerprints. Additionally, your baby’s brain continues to develop, and they may even start to dream.
Week 25-26: Brain Development and Hearing
During weeks 25 and 26, your baby’s brain continues to develop rapidly. They can now form memories and may even start to recognize your voice. Your baby’s hearing also continues to improve, and they can now respond to sounds outside the womb. Additionally, your baby’s eyes begin to open and close, and they start to develop a regular sleep-wake cycle.
Week 27-28: Rapid Growth and Positioning
During weeks 27 and 28, your baby experiences another growth spurt. They may start to position themselves head down in preparation for birth. Additionally, your baby’s kidneys are now fully functional, and they can excrete urine into the amniotic fluid.
Week 29-30: Bone and Muscle Development
During weeks 29 and 30, your baby’s bones and muscles continue to strengthen. They may be able to move more vigorously, and you may be able to see limbs protruding from your belly at times. Additionally, your baby’s eyes begin to develop the ability to distinguish light from dark.
Week 31-32: Weight Gain and Taste Development
During weeks 31 and 32, your baby continues to gain weight rapidly. They may also develop a preference for sweet flavors, as their taste buds continue to develop. Additionally, your baby’s skin becomes smoother as they start to accumulate more fat under their skin.
Week 33-34: Breech and Head Positioning
During weeks 33 and 34, your baby’s head may start to move down into the pelvic area in preparation for birth. However, some babies may still be breech at this point, meaning that their head is up near the mother’s ribs. Additionally, your baby’s immune system starts to develop, and they begin to produce antibodies to fight off infection.
Week 35-36: Rapid Brain Growth and Delivery Preparation
During weeks 35 and 36, your baby’s brain experiences rapid growth. They may also start to move down into the birth canal in preparation for delivery. Additionally, your baby’s digestive system is fully functional, and they can now process nutrients from breast milk or formula.
Week 37-38: Final Preparations for Birth
During weeks 37 and 38, your baby is considered full term and is ready for birth. They continue to grow and gain weight, and their lungs and other organs are fully developed. As the due date approaches, your baby may drop lower into the pelvis, making it easier for them to be born.
Week 39-40: Delivery Time
During weeks 39 and 40, your baby is fully developed and ready for delivery. The due date is an estimate, however, and many babies arrive a little early or a little late. Once your baby is born, they will continue to grow and develop rapidly in the outside world.
