Every stage of development is critical, turning a cluster of cells into a fully formed human being. In this article, we will explore the development stages of a baby in the womb.

Week 1 and 2: Conception and Implantation
A baby’s life begins at conception. On the first day of your last menstrual cycle, the egg is released from your ovary and moves down the fallopian tube, where fertilization may occur. Once the egg is fertilized, it forms a single cell called a zygote. The zygote then divides, forming a ball of cells that travel down the fallopian tube towards the uterus. By the end of the second week, the ball of cells – now called a blastocyst – has implanted into the uterus lining.
Week 3 to 4: Formation of Major Organs
During the third week of pregnancy, the blastocyst begins to form three distinct layers – the ectoderm, mesoderm, and endoderm. These three layers will eventually become all of the major organs and body parts. By the end of the fourth week, the baby’s heart has started to beat, and the neural tube – which will eventually form the brain and spinal cord – is forming.
Week 5 to 8: Fetal Development
During weeks five to eight, the embryo transforms into a fetus. At this stage, the fetus’s major organs and systems are forming – including the digestive, circulatory, and nervous systems. The fetus also begins to develop fingers and toes, and its heartbeat can be detected through an ultrasound. The sex of the baby can also be determined at this stage.
Week 9 to 12: Growth and Development
Weeks nine to twelve are the beginning of the fetal period, where the baby’s major systems are formed and are now starting to mature. The baby’s organs and limbs are growing, and their movements are becoming more coordinated. The baby’s skin is now transparent, and you may see their blood vessels through it. The baby can also make facial expressions at this stage.
Week 13 to 16: Senses Develop
During weeks 13 to 16, the baby’s senses begin to develop. They can now hear sounds, and their eyes begin to move beneath their closed eyelids. The baby can also suck its thumb and make other small movements, such as squinting and frowning. The baby’s head is still proportionally larger than its body, but it’s starting to even out.
Week 17 to 20: Developing Personality
During weeks 17 to 20, the baby’s personality begins to develop. They have unique fingerprints, and their hair and nails are growing. The baby may even have hiccups, which you may feel as small jerks inside your womb. The baby’s movements are becoming more frequent and stronger.
Week 21 to 24: Viability
At 21 weeks, the baby’s lungs are developing, and they can breathe amniotic fluid to practice breathing. By weeks 23-24, the baby is considered viable, meaning that they have a chance of survival outside of the womb. The baby’s eyes are now open, and they can distinguish between light and dark.
Week 25 to 28: Brain Development
During weeks 25 to 28, the baby’s brain is developing rapidly. The baby is now able to dream and has a regular sleep cycle. The baby’s body is also starting to fill out, and it’s getting harder to see their movements through your belly.
Week 29 to 32: Final Growth Spurt
During weeks 29 to 32, the baby is going through a final growth spurt. Their lungs are almost fully developed, and they can regulate their body temperature. The baby’s movements are now more limited due to their size, and you may feel more pressure on your bladder and other organs.
Week 33 to 40: Final Preparations
During weeks 33 to 40, the baby is getting ready to be born. They may move into the head-down position for birth, and their body is filling out to prepare for life outside the womb. Their eyes may now blink and open widely, and they may even have a full head of hair. The baby’s movements are now less frequent, as they are running out of room in your uterus.
Pregnancy is a remarkable experience that results in the creation of a new life. Watching your baby grow and develop inside your womb is a miraculous event. Each stage of development is essential, and we hope this guide provides you with insight into the wonder of fetal development.
