Can I add to the refrigerated breastmilk that I expressed this morning?

My baby is two weeks old and I have just started to express milk. My question is: Can I add to the refrigerated breastmilk that I expressed this morning? Also, what is the 800 number for calling and asking questions?

Congratulations on the birth of your baby! It can be confusing to keep track of how to store breastmilk. It is fine to add to the breastmilk that you've previously expressed during the day if you follow a few simple guidelines.

The Breastfeeding Answer Book says "A mother need not keep separate batches of milk expressed at different times during the day, provided the previous batches have been stored between 32 and 60 degrees Fahrenheit." It also says "Fresh milk can be added to already frozen milk if it is cooled first and there is less fresh milk than frozen milk."

The La Leche League International Webpage at has lots of information about breastfeeding basics, including breastmilk storage. From that website you will also find a directory of many Leaders that may list one in your community. If you are unable to find a Leader through the directory you can try phoning 1-800-LA LECHE in the United States. I hope you find a local group, as our meetings are a wonderful way to share concerns, encouragement, and connect with other new mothers. Enjoy your new baby!
