Parents who are happy to welcome their babies must be particularly concerned about the baby’s weight, how much is normal for a full-term newborn to weigh? A normal newborn weighs about 2.5-4.0kg at birth and is about 50cm long. It usually loses about 5-8% of its weight in the first few days after birth, but regains its birth weight level within 2 weeks. Then from then until 3 months, their weight increases by 10-15g/Kg per day. mothers who insist on breastfeeding during the period from newborn to full term will also gradually increase their milk during this time, and most of them will be able to feed their babies exclusively through breast milk. At full term, the baby’s weight can increase by about 1 kg on average compared to the birth, and the length also grows by 3-4 cm on average. Some babies who grow well gain more than 30 grams of weight per day. Male babies can weigh 3.7-6.1kg, with an average of 4.9kg, while female babies may be slightly lighter, reaching 3.5-5.7kg, with an average weight of 4.6kg. Of course, moms and dads should note that this is only an average value, and there are individual differences in baby growth to a large extent. Moms and dads must not blindly pursue their baby’s weight gain, knowing that many adult diseases are caused by obesity in infancy! As long as your baby has a good spirit, a strong appetite and good motor development, there is no need to worry even if the weight does not reach the standard value.
