How do I use before-feed and after-feed weights to calculate how much milk my baby takes from the breast?
If mothers want to use before-feed and after-feed weights to see how much milk their baby is taking in from the breast, the baby should be weighed before and after every breastfeed for at least one 24-hour period. Total daily intake of breast milk and supplement is measured by calculating the difference between the weights of the baby before and after breastfeeding and adding the amount of supplement taken in. Intake varies from one feed to the next and from day to day. That’s why we recommend doing this over two 24-hour periods. The typical amount of milk and milk supplement that babies need to grow well depends on the baby’s age and size and varies between babies of the same age.
