Pumping and Storing Your Milk

It can be helpful to know how to pump and store your milk. If you are unable to feed your baby at the breast, it is important to remove milk to tell your body to make milk.

AFTER EACH PUMPING

  • Label the storage container with the date, the amount of milk being frozen, and your baby's name
  • Chill, refrigerate, or freeze milk right after it is expressed depending on when it will be used
  • Human milk can be stored in an insulated cooler bag with an ice pack for up to 24 hours

Tips For Freezing Milk

  • Freeze human milk in small amounts of 2 to 4 ounces (or the amount that will be offered at one feeding) to avoid wasting milk that might not be finished.
  • Try to leave an inch or so between the milk and the top of the container because milk expands when frozen.
  • Store milk in the back of the freezer.

Tips For Thawing and Warming Milk

  • Do not microwave breastmilk. Microwaving milk creates hotspots that could burn your baby and can damage the nutrients in your milk.
  • Use the oldest stored milk first.
  • You can thaw frozen milk in the refrigerator overnight, or hold the frozen bag of milk under warm running water, or set in a container of warm water. Test the temperature by dropping a little on your wrist.
  • Find the right milk temperature for your baby. Human milk does not necessarily need to be warmed. Some moms prefer to take the chill off and serve at room temperature.
  • Swirl human milk to mix the fat. Shaking the milk is not recommended because it can break down certain nutrients.
  • Use thawed human milk within 24 hours (this means from the time it is no longer frozen or completely thawed, not from the time you took it out of the freezer). Do not refreeze thawed human milk.

Safely Clean Pump Equipment

  • Take apart pump tubing and separate all parts that come in contact with your breast and milk.
  • Do not wash tubing. Tubing should not come in contact with your milk or breast so it does not need to be cleaned.
  • Rinse the pump parts by holding them under running water to remove remaining milk.
  • Do not place or wash parts in the sink. Germs in the sink could contaminate items.
  • Clean pump parts in a dishwasher or by hand in a clean basin with soap and hot water.
  • Air dry the items on a clean dishtowel, paper towel, or bottle drying rack.
  • Using clean hands, store the parts in a clean, protected area.
  • Discard and replace moldy tubing immediately.
  • Pump kits and most pumps should not be shared between users.

Sanitize for added safety:

Sanitize pump parts, wash basin, and bottle brush at least once daily after they have been cleaned. Items can be sanitized using steam, boiling water, or a dishwasher with a sanitize setting.

Sanitizing is very important if your baby is less than 3 months old, was born prematurely, or has a weakened immune system due to illness or medical treatment.

EXTRACCIÓN MANUAL

Cómo funciona

Con las manos limpias, ahueque su seno en forma de C (como se muestra en la imagen), pero sin tocar la areola. Presione sus dedos firmemente hacia su pecho. Luego, comprime tu mano mientras la mueves hacia el pezón sin levantar la mano del seno. Repita y pruebe diferentes posiciones en sus senos para que pueda sacar leche de diferentes conductos galactóforos.

¿Qué está involucrado?

  • Requiere práctica, habilidad y coordinación.
  • Se vuelve más fácil con la práctica y puede ser tan rápido como bombear.
  • Es bueno si no estás lejos de tu bebé con frecuencia o si necesitas una opción que esté siempre contigo. Todas las mamás deben saber cómo extraerse la leche manualmente, en caso de que necesiten hacerlo inesperadamente.
  • Puede hablar con el experto en lactancia de su oficina local de WIC para obtener consejos sobre cómo realizar la extracción manual.

EXTRACCIÓN CON EXTRACTOR MANUAL

ELECTRIC BREAST PUMP

How it works

Runs on battery or plugs into an electrical outlet.

  • Need a place to clean and store the equipment between uses.
  • If you have insurance, they may cover the cost of a pump. You can also talk to your local WIC office about renting a pump.

Cómo funciona

Funciona con batería o se conecta a una toma de corriente.

Costo promedio

$150 a más de $250 (a menudo, lo cubre el seguro)

HAND EXPRESSION

How it works

Using clean hands, cup your breast using a c-hold (as pictured) but not touching your areola. Press your fingers firmly back towards your chest. Next, compress your hand while moving it back towards your nipple without lifting your hand from your breast. Repeat and try different positions on your breasts so you can get milk out of different milk ducts.

What’s Involved

  • Requires practice, skill, and coordination.
  • Gets easier with practice and can be as fast as pumping.
  • Good if you are not often away from your baby or you need an option that is always with you. All moms should know how to hand express, in case they need to do it unexpectedly.
  • You can talk to your local WIC office breastfeeding expert for tips on how to perform hand expression.
