From the Guidelines

A healthy 2-month-old baby should typically gain about 1.5 to 2 pounds (680-900 grams) per month during this period, which translates to approximately 5-7 ounces (140-200 grams) per week, as indicated by the most recent guidelines 1. To ensure adequate weight gain, parents should track the baby's weight at regular pediatric check-ups, which are typically scheduled at 1,2,4,6,9, and 12 months of age. Some key points to consider for adequate weight gain in a 2-month-old baby include:

  • Feeding frequency and volume: For breastfed babies, feeding should occur 8-12 times per day (every 2-3 hours), while formula-fed infants usually need about 3-4 ounces per feeding, 6-8 times daily, as recommended by pediatric health guidelines 1.
  • Monitoring wet diapers and bowel movements: Parents should monitor wet diapers (6-8 per day) and bowel movements as indicators of adequate intake.
  • Consultation with a pediatrician: If weight gain remains below expectations despite appropriate feeding, consultation with a pediatrician is essential to rule out underlying medical issues such as feeding difficulties, digestive problems, or other health concerns. It is also important to note that the World Health Organization (WHO) growth charts, which are recommended for use in children under 24 months, show different growth patterns compared to the CDC charts, and may lead clinicians to different conclusions about variations in growth 1. However, the most recent and highest quality study 1 provides the best guidance for adequate weight gain in a 2-month-old baby.

From the Research

Recommendations for Adequate Weight Gain in a 2-Month-Old Baby

  • A satisfactory gain in the infant's weight is the best way to judge the adequacy of the diet of the infant 2
  • The American Academy of Pediatrics (AAP) recommends exclusive breastfeeding for approximately 6 months after birth, and continued breastfeeding along with appropriate complementary foods introduced at about 6 months 3
  • Breastmilk is the best food for newborns and infants, and its nutritional composition is fairly constant, regardless of the mother's diet 2
  • Mothers should be advised to consume a mixed diet, and should not receive less than 1800 calories per day 2

Factors Affecting Weight Gain

  • Antenatal care visits have been associated with exclusive breastfeeding and adequate feeding practices in infants 4
  • Introduction of complementary foods at the right time, and avoidance of unnecessary foods and drinks, can help support adequate weight gain in infants 5
  • Breastfeeding mothers should be supported and encouraged to continue breastfeeding, as it provides numerous benefits for the infant's growth and development 3

Monitoring Weight Gain

  • Regular postnatal visits are essential to monitor the infant's weight gain and provide guidance on feeding practices 2
  • Pediatricians play a critical role in advocating for breastfeeding and providing guidance on adequate feeding practices 3
