When to Do 4D Ultrasound: Everything You Need to Know

Technology has revolutionized the field of healthcare, providing us with incredible tools to monitor the health and development of unborn babies. One such advancement is the 4D ultrasound, a technique that allows expectant parents to see their baby’s movements and facial features in real time. While traditional 2D ultrasounds provide valuable information, 4D ultrasounds offer a more immersive and detailed experience. But when is the best time to schedule a 4D ultrasound?
