A Guide to Combination Feeding: Supporting Your Breastfeeding Journey
What is Combination Feeding:
Breastfeeding, Pumping, and Formula Feeding
Combination feeding (also called supplementing) means feeding a baby with a mix of breastmilk (either directly from the breast or pumped) and formula. Families may choose this approach for many reasons, and it can be done in a way that supports both breastfeeding goals and baby’s nutritional needs.
How Combination Feeding Impacts Milk Supply
Milk supply is regulated by demand, so the way combination feeding is structured can influence how much milk is produced:
If breast milk is removed regularly (via direct nursing or pumping), supply is maintained.
If formula replaces breastfeeding sessions without pumping, supply may decrease over time because the body is getting fewer signals to make milk.
Some parents use combination feeding short-term (e.g., supplementing while working on latch or milk supply) and then return to full breastfeeding. Others will use formula to wean off breastfeeding and pumping entirely. This decision and the plan is very personal choice and can be highly individualized!
Is Combination Feeding Right for Your Family?
It depends on:
Your feeding goals – Do you want to maintain a strong milk supply or gradually reduce breastfeeding?
Your baby’s needs – Does your baby need extra supplementation due to medical reasons, growth concerns, milk supply or intake issues?
Your lifestyle – Do you need flexibility for work, family support, or personal reasons and don’t want to pump?
Your mental & physical well-being – Does combination feeding reduce stress and make feeding more manageable for you? Your happiness is important too!
There’s no one-size-fits-all answer, and an IBCLC can help tailor a plan to fit your specific situation.
Why Do Families Choose to Combination Feed?
Low milk supply – Some parents don’t produce enough milk and need to supplement.
Medical reasons – Baby may have weight gain concerns, jaundice, or need extra calories or volume.
Returning to work/school – Parents may not be able to pump as often and choose formula for some feeds.
Partner involvement – Other caregivers can help with feeding, allowing more flexibility.
Parental preference – Some parents find combination feeding works best for their lifestyle and mental well-being.
