Babies are born in different shapes and sizes. Their weight may also vary. But everything has an average or standard. The average baby weight of a baby in his or her full-term is seven pounds and five ounces, but babies can be born with more or less weight than this average baby weight. Over the course of time, your baby should grow and his or her weight should also grow. Average baby weight is a vital sign that your baby is growing up properly. At every visit to your pediatrician, the doctor will monitor weight, length, and head size to be sure whether the average baby weight of your baby is progressing in the right way or not.

Final Words
Being underweight or overweight than the above standard average baby weight does not mean that your baby will remain underweight or overweight for his or her entire life or that he or she has any health problem. Newborn babies lose some weight within their first few days of birth because they are born with some extra fluids which they quickly emit. They regain the weight shortly afterward within a few weeks and next, their weight gain may slow down sometimes, but most babies gain double weight of their birth weight within their first five months.
The factors that affect average baby weight are genetic reasons, length of pregnancy, nutrition during pregnancy, lifestyle during pregnancy, sex of your baby, health condition of the mother during pregnancy, number of babies in the womb at a time, the health of your baby, and birth order.
