Fetal weight can vary, but on average, a baby weighs around 2.7-3.8kg at birth. At 32 weeks, a weight of 2.6kg is within the normal range, although it may be on the lower side. It's important to remember that every pregnancy is different and there are various factors that can influence fetal weight, such as genetics and maternal health. If you have concerns about your baby's growth, it's best to consult with your healthcare provider who can assess your specific situation and provide appropriate guidance and support. They may recommend additional tests or monitoring to ensure the well-being of both you and your baby.
