During pregnancy, the development of a baby's brain, eyes, and major organs is a complex process that occurs over several weeks. By week 6, important groundwork has already been laid for these vital structures. The brain begins its formation early in pregnancy and continues to develop throughout gestation. At this stage, the neural tube is closing, which will eventually become the spinal cord and brain. Major organs such as the heart, lungs, liver, kidneys, and digestive system are also starting to form during this time. Over the next few weeks and months, these structures will continue to grow and mature. It is important to note that each baby develops at their own pace; therefore, individual variations may occur in terms of timing and progression of organ development. Regular prenatal care with your healthcare provider can help monitor your baby's growth and ensure optimal development.
