Newborn baby weights can vary depending on a variety of factors, but the average weight of a newborn, male or female, is between 5 pounds 8 ounces and 8 pounds 13 ounces. However, baby girls are often smaller than boys at birth, but only slightly.
Most babies double their birth weight by 5 months of age and triple their birth weight by the time they're 1 year old. The average weight of a 6-month-old is about 16 pounds (7.3 kg), and the average weight of a 1-year-old is approximately 21Â½ pounds (9.8 kg). Boys may be bigger than girls, and breastfed infants may weigh less than formula-fed infants.
