Last medically reviewed on September 7, 2021 And by taking a detailed medical history, they can rule out any medical conditions or nutritional considerations that may be preventing a baby from gaining weight appropriately. Healthcare professionals also take into account whether a baby is generally hitting other milestones on time. Knowing about average weights by month can help people gauge their babies’ physical development, but doctors also look for other important indicators, such as length and head circumference.

And even if a baby’s weight is in a lower percentile, they will not necessarily be a small adult - just as longer babies do not necessarily become tall adults. Still, a doctor usually looks for steady growth, rather than a target percentile, when assessing a baby’s physical development. For female babies born full-term, the average birth weight is 7 lb 2 oz, or 3.2 kg.īaby weight charts can help a healthcare team track a baby’s physical development by comparing the baby’s weight with the weights of others of the same age and sex. The average birth weight for full-term male babies is 7 lb 6 oz, or 3.3 kg. However, many babies born prematurely gain weight rapidly and “catch up” by about their first birthday.

Prematurityīabies born prematurely may grow and gain weight more slowly during their first year than babies born at full term. Health issues that affect nutrient absorption or digestion, such as celiac disease, may also lead to slow weight gain. For example, babies with congenital heart irregularities may gain weight at a slower rate than babies without this condition. Underlying health issues can cause a baby to gain weight more slowly. Breastfed babies may gain weight and grow more slowly than formula-fed babies when they are aged 6 months to 1 year. However, that rate can shift during the next 6 months. The American Academy of Pediatrics notes that breastfed babies gain weight and grow faster than formula-fed babies during the first 6 months. Weight gain and growth rates can also depend on whether the baby consumes breast milk or formula. Male newborns tend to be bigger than female newborns, and they typically gain weight a little faster during infancy. Various checklists of milestones by age are available, including one from, which is endorsed by organizations such as the American Academy of Pediatrics and the National Association of Pediatric Nurse Practitioners.įor anyone looking for more information about what influences the weight of a baby, several factors can be involved, including: Sex Meanwhile, it is also important to keep other developmental milestones in mind. Other measurements of this development include the baby’s length and head circumference.Ĭonsidering all three measurements gives doctors an idea about how the baby is growing, compared with other babies of the same age and sex.

It is important not to focus on weight as the only indicator of physical development.
