Can I Mix Formula Milk And Breast Milk

While there’s nothing wrong with mixing breast milk and formula in the same container, it’s not recommended simply because you don’t want to waste a single drop of your precious breast milk. Formula from a bottle that your baby has drunk from must be discarded within an hour of preparation.

While it is OK to put breast milk and formula in the same bottle if you have already prepared the formula, mixing them can lead to wasted breast milk if your baby does not finish the bottle. If possible, give breast milk first, then finish the feeding with formula.
