Weeks 1-4: Conception and Implantation
The journey of baby in the womb development begins with fertilization. When a sperm fertilizes an egg, the resulting zygote travels through the fallopian tube, dividing into multiple cells as it goes. Once it reaches the uterus, it implants in the lining, which triggers the release of hormones that signal pregnancy.
During these early weeks, the placenta begins to form, which will ultimately provide essential nutrients and oxygen to the developing baby. By the end of the fourth week, the embryo is about the size of a poppy seed and has developed the early structures of the brain, spinal cord, and heart.
Weeks 5-8: Organ Development
At this stage of baby in the womb development, the embryo is now called a fetus. The fetus is about an inch long and has developed tiny fingers, toes, and facial features. The major organs also start to form during this stage, including the liver, kidneys, and lungs.
At the end of the eighth week, the fetus is about the size of a grape and can officially be called a baby. The heart is fully-formed and beats at a steady pace, and the baby can even start to move around in the womb, although the mother may not feel it yet.
Weeks 9-12: Growth and Movement
During this stage of baby in the womb development, the baby’s growth really starts to take off. By the end of the twelfth week, the baby is about the size of a lime and weighs around half an ounce. The fingers and toes are fully-formed, and the baby can make a fist and even suck its thumb.
The baby’s nervous system also starts to develop during this stage, allowing the baby to move its limbs and facial muscles. These movements are essential for the baby’s overall development, as they help build strength and coordination.
Weeks 13-16: Gender and Hair
Around this point of baby in the womb development, the baby’s gender can be determined via ultrasound. The baby’s body is covered in a fine hair called lanugo, which helps regulate body temperature and protect the skin.
By the end of the sixteenth week, the baby is about the size of an avocado and weighs around three ounces. The baby’s facial features become more distinct, and it can hiccup, yawn, and even suck its thumb.
Weeks 17-20: Senses and Teeth
During this stage of baby in the womb development, the baby’s senses start to develop. The baby can hear sounds from outside the womb, and its eyelashes and eyebrows start to grow. Teeth also start to form under the gums.
By the end of the twentieth week, the baby is about the size of a banana and weighs around ten ounces. The baby’s skin starts to become less transparent, and the mother can feel the baby’s movements more regularly.
Weeks 21-24: Brain Development and Breathing
During this stage of baby in the womb development, the baby’s brain starts to develop rapidly. The baby can also blink its eyes and has fully-formed fingerprints. The lungs start to develop the air sacs necessary for breathing.
By the end of the twenty-fourth week, the baby is about the size of an ear of corn and weighs around one-and-a-half pounds. The baby’s skin becomes less wrinkled, and the eyes start to move back and forth.
Weeks 25-28: Sleep and Dreams
During this stage of baby in the womb development, the baby’s sleep patterns become more regular, and it spends much of its time sleeping and dreaming. The baby’s lungs continue to mature, and it starts to develop more body fat.
By the end of the twenty-eighth week, the baby is about the size of a head of cauliflower and weighs around two-and-a-half pounds. The baby’s eyes can respond to light, and it can make more complex facial expressions.
Weeks 29-32: Growth and Development
During this stage of baby in the womb development, the baby’s growth rate slows down slightly as it starts to fill out. The baby’s bones become harder and its movements more deliberate.
By the end of the thirty-second week, the baby is about the size of a butternut squash and weighs around four pounds. The baby’s skin becomes less red and wrinkled, and it can open and close its eyes.
Weeks 33-36: Final Preparations
During this stage of baby in the womb development, the baby is making final preparations for birth. It moves into a head-down position and starts to store fat to regulate its body temperature after birth.
By the end of the thirty-sixth week, the baby is about the size of a honeydew melon and weighs around six pounds. The baby’s liver and immune system are fully-formed, and it can even respond to music and sounds outside the womb.
Weeks 37-40: Ready for Birth
During this final stage of baby in the womb development, the baby is considered full-term and ready to be born. It may still gain a bit more weight during these last few weeks, and the mother may experience Braxton Hicks contractions that help prepare her body for labor.
By the end of the fortieth week (or a little before or after), the baby is fully-formed and ready to meet the world. Its journey from conception to birth is complete, and a new chapter in its life is about to begin.
