Breastfed Babies Weigh Less

• Babies who breast feed gain about four to seven ounces a week in the first month of life, and one to two pounds after that until about six months. This is the same rate that formula fed babies gain weight. However, after six months of age, breastfed babies gain less weight than formula fed babies, averaging about one pound per month.
  
  

Infant Weight Gain Depends on Variables

• Breastfed babies who are allowed to nurse on demand and those who co-sleep with their mom often gain weight quicker than those who are sleep trained or fed on a schedule. A baby's body type and his metabolic rate influence the weight gain as well. Babies who are active gain less weight, and those who are more laid back gain more.
  
  

Bottom Line

• Breastfed babies should gain weight more quickly in the first three to four months of life. After this, the rate of weight gain may decrease. Standard growth charts reflect formula fed infants, so if you or your doctor is concerned about a decrease in your breastfed baby's weight gain, make sure your doctor knows you are breastfeeding. Breastfed babies are able to regulate how many calories they ingest, and therefore eat exactly what they need to grow.
