At 34 weeks of pregnancy, the average fetal weight is around 2.1-2.5 kg (4.6-5.5 lbs). Your baby's weight of 2.4 kg falls within this range, which suggests that your baby's growth is on track. However, it is important to note that every pregnancy is unique, and individual factors such as genetics and maternal health can influence fetal weight. If you have any concerns about your baby's growth or if your healthcare provider has expressed any concerns, it is recommended to discuss them with your doctor or midwife for further evaluation and guidance.
