Baby Development
Forty weeks into pregnancy, your baby might have a crown-to-rump length of around 14 inches (360 millimeters) and weigh about 7.5 pounds (3,400 grams). But remember that healthy babies come in lots of sizes. Don't be worried if your due date comes and goes with no signs of labor starting. The due date is simply an estimate of when your pregnancy will be 40 weeks along. It doesn't predict exactly when your baby will arrive. Many people give birth before or after their due dates.

Congratulations on reaching the remarkable milestone of 40 weeks of pregnancy! At this stage, your baby is fully developed and ready to make their grand entrance. You may notice heightened fetal activity, especially at night, as your baby navigates the limited space within the womb. This increase in perceptible movements, including powerful kicks and rolls, is a sign of your baby's strong neuromuscular development. It's a good time to focus on your maternal instincts and listen to your body's signals. While you may be experiencing discomfort and fatigue as your body continues to prepare for labor, recognize that baby’s nighttime activity might be more noticeable due to the quiet environment. To promote comfort, try to maintain a balanced, nutrient-rich diet and engage in light physical activity, such as walking or prenatal yoga, if it feels right for you. These practices can help manage symptoms of heartburn or digestive issues which are common now. Stay hydrated and continue with your prenatal vitamins to support both your body and your baby’s final developmental needs. Remember, your healthcare provider is there to support you, so don’t hesitate to reach out with any concerns as you approach delivery.
