How much expressed milk does my baby need?

It is best to follow the baby’s lead and use paced bottle feeding practice.1 Volume needs will change from feeding to feeding, from day to day, and from baby to baby. Learning a baby’s unique communication style is an important part of the early bonding process.

General Guidelines2

For babies weighing 2.5 kg or more

  • 150 ml milk per kg of body weight per day
  • Divide the total into 8 feeds, and give 3-hourly

For babies who weigh less than 2.5 kg (Low-birth-weight)

  • Start with 60 ml per kg of body weight
  • Increase the total volume by 20 ml per kg per day, until the baby is taking a total of 200 ml per kg per day
  • Divide the total into 8-12 feeds, to feed every 2-3 시간
  • Continue until the baby weighs 1,800 g or more, and is fully breastfeeding

Check the baby’s 24-hour intake. The size of individual feeds may vary.

The below calculator3 can be used as a guideline for babies that are receiving feeding from an at-the-breast system, a cup, or a bottle. Again, always follow your baby’s hunger and satiation cues

  1. How do I feed the milk to my baby? ↩︎
  2. WHO/UNICEF – Breastfeeding Counselling A Training Course ↩︎
  3. A Baby’s Best Start Nursing Center – Amount of milk needed by baby in 24 시간 ↩︎
  4. These are approximate amounts. Follow your baby’s cues first.
    Oz/feeding = oz/day divided by the number of feedings.
    Example: A 9lb 8oz baby needs 24.8 oz/day. If feeding 8 times a day: 24.8 divided by 8 equals 3.1 oz/feeding. If feeding a baby breastmilk with a bottle, place the calculated amount of milk per serving in separate bottles.
    Daycare:
    Use the chart to calculate how much to take to daycare for the day.
    Example: A 9lb 8oz baby needs +/-24.8 oz/day or 3.1 oz/feeding.
    If daycare requires 3 feedings or 9.3 oz/day or 3.1 oz/bottle/day.
    Pump 9.3 oz at work for the next day at daycare, or use frozen or refrigerated milk. ↩︎
