Pregnancy is an exciting journey for every woman, and watching your baby develop inside you is a fascinating experience. The baby undergoes a multitude of changes during each trimester of pregnancy, and it’s essential to understand these changes to ensure the health and wellbeing of both the mother and the baby.

First Trimester

The first trimester starts from week 1 to week 12 of pregnancy. During this period, the baby develops from a single fertilized cell to a size of a peach. The embryo develops into a fetus and starts to form organs, bones, and muscles. The baby’s heart begins to beat, and the brain and spinal cord start to develop. The baby’s facial features start to form, and the limbs start to grow. By the end of the first trimester, the baby can move its arms and legs.

Second Trimester

The second trimester starts from week 13 to week 28 of pregnancy. During this period, the baby grows rapidly and starts to look like a human being. The baby’s skin becomes less transparent, and the body starts to produce hair. The eyes, ears, and other sensory organs start to function, and the baby can detect light and sound. The baby’s bones become harder, and the muscles become stronger. The baby starts to move more, and the mother can feel the baby’s movements.

Third Trimester

The third trimester starts from week 29 until birth. During this period, the baby’s growth slows down, and the focus shifts to the baby’s development of the organs. The baby’s lungs mature, and the baby starts to practice breathing. The baby’s brain continues to develop, and the nervous system becomes more complex. The baby’s bones become denser, and the body starts to store fat. The baby’s head becomes engaged in the pelvis, preparing for birth.
