umping at work can be challenging, but with some preparation and strategies, you can make it more manageable. Here are some helpful tips for pumping at work:

8.1 Know Your Rights:

    • Familiarize yourself with your rights as a working and breastfeeding mom. The Fair Labor Standards Act (FLSA) mandates that employers provide basic accommodations for nursing moms.
    • The PUMP for Nursing Mothers Act ensures that you have a private place (other than a bathroom) to express breast milk while at work. This right extends up to one year after your child’s birth.
    • Employers must also grant you reasonable break time for pumping until 12 months after delivery.

8.2 Choose The Right Pump:

    • Invest in a quality double-electric breast pump. It’s efficient and worth the cost.
    • Consider renting a hospital-grade electric pump if needed.
  1. Create a Pumping Schedule:
    • Establish a consistent schedule for pumping at work. Coordinate it with your breastfeeding routine at home.
    • Having a routine makes balancing work and pumping easier.
  2. Find a Suitable Location:
    • Scout out a private, quiet space where you can pump comfortably. It should be shielded from view and not a bathroom.
    • Communicate your needs to your employer; they must comply with the law.
  3. Stay Hydrated and Nourished:
    • Keep a bottle of water at your desk. Breastfeeding requires hydration.
    • Have healthy snacks on hand to replenish the calories your body uses for milk production.
  4. Label and Store Milk Properly:
    • Label each container with the date of expression.
    • Store milk in a cool, clean place (such as a refrigerator or insulated cooler).
  5. Take Care of Yourself:

11. Breast Milk Statistics

Let’s explore the nourishing world of breast milk through the lens of data and statistics. Whether you’re a curious parent, a health enthusiast, or simply intrigued by the magic of lactation, these numbers offer insights into this remarkable elixir.

11.1 United States Breastfeeding Statistics (2022):

  1. Breastfeeding Initiation: Among infants born in 2019,  83.2% started out receiving some breast milk. That initial connection, the first sip of liquid love is a powerful one.
  2. Continued Breast Milk: At 1 month78.6% of babies were still receiving any breast milk. Imagine those tiny mouths, eagerly latching on, nourished by nature’s bounty.
  3. Six-Month Mark: As we hit the 6-month milestone, 55.8% of infants continued to receive any breast milk. And of these, 24.9% enjoyed the exclusive embrace of breast milk alone1.

Now, let’s ponder the complexities. Families face hurdles, sleepless nights, cracked nipples, and the delicate balance of life. Yet, these numbers reveal resilience. Most infants begin their journey with breast milk, and many persist at the 6-month mark. Even a sip matters, a drop of immunity, a swirl of nutrients.

But here’s the twist: disparities persist. Across races and ethnicities, breastfeeding experiences vary. We’re on a quest to bridge these gaps, to ensure every baby feels the warmth of liquid gold. Because in this dance of data, we see a rhythm, a steady decline from month to month. It whispers: “Support us better. Strengthen our systems.”

11.2 Australian Breastfeeding Snapshot (2022):

  1. Ever Received Breast Milk: In the land Down Under, 90.6% of children aged 0–3 years have tasted this liquid marvel. It’s like a symphony of sustenance, echoing across cribs and nurseries.
  2. Two Months In: At the tender age of 2 months83.5% still bask in the embrace of breast milk. And of these, nearly 73.5% experience the exclusivity—their tiny mouths savoring nature’s blend2.

Why does it matter? Because every drop counts. Exclusivity matters. Low rates of breastfeeding ripple beyond nurseries, they add over $3 billion annually to medical costs for mothers and children in the United States. And let’s not forget: 77% of Black infants ever breastfeed, below the national average of 83%2.

So, dear parents, whether you’re expressing by hand or humming with an electric pump, know this: you’re part of a global symphony. Your milk, liquid resilience shapes futures. And as these numbers dance, let’s keep the rhythm alive.


In conclusion, mastering the art of breast milk storage is essential for every breastfeeding parent. By following proper guidelines, you can ensure that your baby receives the best nutrition even when you’re not physically present.

First, a gentle reminder: never store breast milk in the freezer door, it’s too prone to temperature fluctuations. Instead, opt for the back of the freezer, where the chill remains steadfast. When you’re ready to thaw, place the frozen milk in the refrigerator. Yes, patience is a virtue, especially when it comes to thawing. Allow it to transform from icy to liquid, like a magical metamorphosis.

Think of it as a graceful waltz; the milk swirls, and your baby’s hunger pirouettes away.

Keep in mind to choose the right containers, label them accurately, and adhere to hygiene practices. Whether you’re pumping at work or storing milk for emergencies, these strategies will help you maintain the quality and safety of your breast milk.
