Introduction
As soon as you find out you are pregnant, you start to wonder about your little one’s development. You may have questions like, when does a baby first develop? How does the baby grow? What are the stages of development? As a mom-to-be, it’s essential to understand how your baby develops from conception to birth.
Conception
The journey of development starts with conception. At this point, the sperm meets the egg, and fertilization takes place. Your baby’s DNA is determined at this point, and gender is established. The fertilized egg is known as a zygote and starts to divide into multiple cells.
First Trimester
During the first trimester, the zygote travels down the fallopian tube and implants itself in the uterus. This process usually occurs around six to ten days after conception. At this stage, the baby is known as an embryo. The embryo’s heart starts to beat, and the baby’s organs begin to form. By the end of the first trimester, the embryo is about 3 inches long and weighs around 1 ounce.
Second Trimester
The second trimester is a critical period for the baby’s development. At this stage, the baby is known as a fetus. The fetus starts to move and can be seen on an ultrasound. The baby’s bones start to harden, and the skin becomes less transparent. The fetus starts to grow hair and nails. By the end of the second trimester, the fetus is about 14 inches long and weighs about 2 pounds.
Third Trimester
The final trimester is all about growth and development. The fetus’s lungs and brain continue to develop, and the baby starts to store fat. The fetus’s movements become more frequent as space becomes more limited. By the end of the third trimester, the baby is fully formed and ready for birth.
