The milk storage guidelines listed here are for healthy babies who are at home. If your baby is in the hospital (preterm or sick), check with your baby’s health care provider to find out what milk storage guidelines they recommend.
- Keep in mind that fresh milk is best. If you have stored milk at room temperature and are going to miss a breastfeeding session with your baby, give the milk stored at room temperature first.
- If you plan to use your milk within 8 days, you can keep it in the fridge. Otherwise, plan to freeze it in the coldest part of the freezer. Avoid storing your milk in the door.
- If you follow the times on the chart below, you can keep your milk at room temperature, then refrigerate it, and then freeze it.
- Before freezing large amounts of milk. Freeze a batch or two, then thaw and smell it. Some mothers make milk high in lipase, an enzyme that digests fat. When thawed, the frozen milk of these moms has a strong, soapy smell. If this happens and the baby refuses this milk, deactivate the lipase before freezing it by scalding the milk first. (To scald your milk, heat it in a pot on the range until bubbles form at the edges, then cool and freeze.)
