Northwest Family Clinics - Everything to know about pumping

Having a baby is truly one of the most exciting things in life, but for many of us, it's taking a step into the completely unknown. As new parents, we are faced with many decisions and questions. One of the many things for a mother to consider is whether she will breastfeed.

Breastfeeding is a wonderful way to nourish your baby, but it's not always possible to breastfeed directly. Whether you're returning to work, managing supply issues, needing to carefully monitor Baby’s intake, or simply need a break, pumping breastmilk can be a great solution. Below, you will find everything to help you easily navigate the world of breastmilk pumping. Here, we'll cover the basics, address common questions, and provide practical tips for successful pumping.

What You Need to Know About Pumping Breastmilk

An excellent place to start is by first fully understanding what it means to 'pump.' This is a process in which a lactating woman, usually after she has given birth, uses a device to extract milk from the breasts. The purpose of breast pumping is often to collect breast milk so that it can be stored and used at a later time, which is especially useful for mothers who are returning to work, are away from their baby for other reasons, or are not engaging in direct breastfeeding.

Pumping can help maintain a mother's milk supply, relieve engorgement (the painful overfilling of the breasts with milk), help to increase milk supply, and allow others to feed the baby with breast milk. It also offers a way to continue providing breast milk to the baby even if breastfeeding directly from the breast is not possible or preferred.

How a Breast Pump Works

Breast pumps can be manual, electric, or battery-operated. They typically consist of a breast shield that fits over the nipple, a pump that creates suction to extract the milk, and a container to collect the milk. The suction mimics the natural sucking motion of a baby and can usually be adjusted to suit the comfort of the mother.

How to Pump

The first step in pumping is to properly put your pump together by carefully reading the instructions. Make sure all parts of the breast pump are clean and sterilized before assembly. Once your pump is assembled, here are some additional tips on how to pump:

  • Choose a comfortable, private place where you can relax. 
  • Before you begin pumping, you might find it helpful to massage your breasts or apply a warm compress to stimulate flow. Make sure your hands are clean before doing so.
  • Place the breast shield (also known as a flange) securely over each breast from which you wish to pump. The nipple should be centered in the shield's tunnel. Ensure a good seal to prevent air leaks, which can affect suction.
  • Turn on the pump, starting with a lower suction setting to get used to the feel. Electric pumps often feature a 'let-down' phase that mimics the quick, light sucking of a baby to stimulate milk flow, followed by a deeper, slower sucking pattern.
  • If your pump allows, adjust the suction level and speed to what feels most comfortable and effective. It shouldn't hurt. If it does, lower the suction.
  • Pump until the milk starts to slow down and your breasts feel emptier, typically about 15-20 minutes. However, this can vary based on your supply and the pump's efficiency.
  • Once you're done, turn off the pump and carefully remove the breast shields. If you've collected milk, make sure to seal it in storage bags or containers and refrigerate or freeze it according to your needs.
  • After each use, it's essential to clean all parts of the pump that came into contact with your breast or milk. Follow the manufacturer's guidelines for cleaning and drying the parts.

Pumping Timing and Frequency

When you pump and how often will vary. If you are still breastfeeding your baby directly, you will not need to pump as often, whereas if you are not breastfeeding at all, you will need to pump more frequently. A normal pumping schedule to maintain your milk supply is generally to pump 8-10 times in 24 hours if you're exclusively pumping. Each session should last 15-20 minutes or until the milk flow stops.  As your baby gets older and can take in more milk at each feed, pumping frequency sometimes decreases, in exchange for pumping out more milk each session.  The best time to pump is usually in the morning when the milk supply is highest. However, you should pump around the same times that your baby normally feeds to maintain your milk supply and avoid discomfort.

Tip: If you’re trying to boost your milk supply, breastfeed your baby on the usual schedule but pump after each feeding.  This increases demand, thus increasing supply.

Common Questions About Pumping Breastmilk

How much milk should I expect to pump?

Output varies widely among mothers. Initially, you might only pump a small amount, but this should increase as your body adjusts to the pump and your baby's needs. A typical session might yield between 0.5 to 4 ounces (15 to 120 ml) from both breasts combined. However, this can vary widely from mother to mother and even day to day and changes as your baby grows.

How can I store pumped breastmilk?

Pumped milk can be stored in clean bottles or storage bags made specifically for breast milk. Here are the general guidelines:

  • Room Temperature: Up to 4 hours is safe.
  • Refrigerator: Store it in the back, where it's coldest, for up to 4 days.
  • Freezer: Store in the back, away from the door, for about six months for best quality.
    • Tip: There are two main types of freezers: one that is adjoined to a refrigerator and a deep freezer.  Deep freezers can store breast milk longer, up to 12 months, because they do not have a defrost cycle (which briefly warms the freezer to prevent frost build up).  Freezers combined with a refrigerator, even if it has a separate compartment/door, can typically store breast milk for less time due to the regular defrosting, about 6-9 months.

Can I mix fresh milk with previously collected milk?

Yes, start by cooling the fresh milk in the refrigerator before adding it to previously chilled or frozen milk. Avoid adding warm milk directly to frozen milk to prevent potential bacterial growth.

What should I do if my milk supply seems low?

Ensure you're hydrated and well-nourished. Try pumping more frequently and for longer sessions. Sometimes, adding a nighttime pumping session can help or pumping after each feed. If concerns persist, talk with your doctor.

Is it normal for pumped milk to vary in color or consistency?

Yes, the appearance of breastmilk can change based on diet, time of day, time since birth (milk is more yellow in the weeks shortly after birth), and pumping frequency. It's normal for milk to vary in color and consistency.

How do I clean my breast pump?

Wash all parts that come into contact with your breast or milk in warm, soapy water. Rinse well and air dry on a clean towel. Consider sterilizing the parts once daily.

Tips for Successful Pumping

  • Stay relaxed, as stress can affect your ability to express milk. Try to pump in a comfortable, quiet environment.
  • Use a setting that's comfortable for you. Don't use the highest suction setting, thinking it will yield more milk. Use the setting that feels most comfortable and most closely mimics your baby's sucking pattern.
  • Consistency is key. Try to pump at the same time each day.

Pumping Requires Practice and Patience

Pumping breastmilk is a skill that takes time to master. Be patient with yourself, and don't hesitate to seek help if you need it. Remember, any amount of breastmilk you provide your baby is beneficial. Remember, your doctor is your number one resource for any questions or concerns you may have. Never be afraid to ask us!
