From conception to birth, these pictures show you how your baby grows

Do you want to know what changes your baby goes through from conception to birth? Today, let's take a look at how the baby develops month by month!


Fertilization occurs when the sperm and egg combine, a process also known as "conception." At this point, the genetic makeup, including the sex of the baby, has been completed. Within about three days after conception, the fertilized egg divides into many cells at a very rapid rate. It travels through the fallopian tubes into the uterus and then attaches to the uterine wall. The placenta, which carries the fetus, also begins to form.

4 weeks of development

Babies at this time are developing the structures of their face and neck. The heart and blood vessels continue to develop. Lungs, stomach and liver begin to develop. Pregnancy test showed positive.

16 weeks of development

Babies are now about 10.9-11.7 cm and weigh about 99 grams. You should be able to feel the top of your uterus to about 7.6 cm below your belly button. The baby can blink and the heart and blood vessels are fully formed. Your baby's fingers and toes have fingerprints.

Babies weigh about 280 grams and are over 15 centimeters long. Your uterus should be flush with your belly button. Babies can suck their thumbs, yawn, stretch and make faces. You will feel your baby move, which is called "fetal movement."

When to do an ultrasound

Ultrasounds of pregnant women are usually done at 20 weeks of pregnancy. During the exam, the doctor makes sure that the placenta is healthy and attached properly, and that your baby is developing normally. You can see the baby's heartbeat and the movements of the body, arms and legs on the ultrasound. The sex of the baby can usually be determined at 20 weeks (of course, the doctor won't tell you).

Development at 24 weeks

Babies now weigh about 635 grams Accelerate your pulse to respond to sounds. If they burp, you may feel the jerking motion. As the inner ear fully develops, the baby in the womb may feel upside down.

There are a few things you can ask your doctor about preterm labor. Now is the time to start your childbirth lessons. Childbirth classes prepare you for all aspects of childbirth, including giving birth and caring for a newborn.

32 weeks of development

Babies weigh about 1815 grams and move a lot. A layer of fat begins to form under the skin of a baby during this period, and his/her skin becomes less wrinkled. Between now and delivery, your baby will gain half of its birth weight. You may notice yellow fluid coming out of your breasts. That's colostrum, the sign that your breasts are ready to make milk. Most women see their doctor every two weeks at this stage of pregnancy.

36 weeks of development

Babies vary in size depending on many factors, such as sex, multiple births, and the size of the parents . Therefore, your baby's overall growth rate is as important as her actual size. On average, babies at this stage are about 47 centimeters and weigh close to 2720 grams. A baby's brain has been developing rapidly. The lungs are almost fully developed. Now, the baby's head is usually located under the pelvis. Your baby is considered "term" at 37 weeks. If they were born between 37-39 weeks, they were slightly preterm, if they were born between 39-40 weeks, they were full term, and if they were born at 41-42 weeks, they were slightly late.


Pregnancy can last 38-42 weeks, with full-term delivery around 40 weeks. If you're more than 42 weeks pregnant, it's not too late. For safety reasons, most babies are delivered before 42 weeks. Sometimes doctors may need to induce labor. The above are the various stages of the baby from pregnancy to birth, I hope it can help you~ Good baby hope that every baby can grow up healthy, happy and safe!
