Start With the Essentials

When I first started breast pumping, I went all out—I bought way more pumping gear than I needed! Looking back, I wish I had just started with the basics and then expanded as I figured out what worked for me.

So, my advice for those just beginning their pumping journey: Start with the must-have pumping essentials. Once you establish a routine and learn more about what makes pumping easier, you can invest in additional accessories that enhance comfort and convenience.

Breast Pump Essentials (Must-Have Accessories)

Here are the breast pumping accessories I recommend every pumping mom starts with:

1. Breast Pump

Let’s start with the obvious—you need a breast pump! There are four main types to choose from:

• Manual pumps – Affordable and great for occasional use (e.g., Haakaa, Medela Harmony).
• Electric pumps – Faster and more efficient for regular pumping (e.g., Spectra S1, Medela Pump in Style).
• Wearable pumps – Hands-free convenience for on-the-go moms (e.g., Momcozy M6, Elvie, Willow).
• Hospital-grade pumps – Powerful suction for exclusive pumping or supply issues (e.g., Medela Symphony, Spectra S3).

2. Correct Flange Size

Your flange (breast shield) size plays a major role in comfort and milk output. An ill-fitting flange can cause pain, nipple damage, and reduced milk expression.

Tip: Measure your nipple size before buying a pump to ensure you get the correct flange size. If needed, flange inserts can help adjust fit, while some brands sell larger or smaller shields separately.

3. Milk Storage Bags or Containers

After expressing, you’ll need a safe way to store your milk:

• Breast milk storage bottles – Ideal for short-term storage or direct pumping.
• Storage bags – Best for freezing and long-term storage; opt for pre-sterilized, leak-proof options.

4. Baby Bottles and Nipples

If you plan to bottle-feed your baby with expressed milk, the right bottle and nipple can make a big difference.

• Breast-like nipples – Mimic the shape and feel of the breast to prevent nipple confusion.
• Slow-flow nipples – Help regulate milk flow to match breastfeeding.
• Anti-colic features – Some bottles have built-in venting systems to reduce gas and fussiness.

5. Cleaning & Sanitization Essentials

Keeping pump parts and bottles clean is essential for your baby’s health. Must-have cleaning supplies include:

• Bottle brushes – For deep cleaning bottles and pump parts.
• Sterilizers or steam bags – Quick and easy way to sanitize.
• Pump wipes – Great for on-the-go cleaning when you can’t wash parts right away.
• Bottle drying rack – Helps keep pump parts sanitary while drying.

Breast Pump Accessories That Make Pumping Easier (Nice-to-Haves)

These items aren’t essential, but they can make your pumping sessions more comfortable and convenient:

1. Hands-Free Pumping Bra

A hands-free pumping bra lets you pump without holding the flanges in place, allowing you to multitask. If you’re using a wearable pump, opt for a stretchy bra that keeps the pump secure without excessive compression.

2. Breast Pump Carrying Bag

If you pump on the go, a breast pump bag keeps your pump and accessories organized. Some bags also have insulated compartments for storing expressed milk.

3. Cooler Bags & Ice Packs

A cooler bag with ice packs is a must if you pump away from home and need to keep milk cold before storing it in a fridge or freezer.

💡 Traveling with breast milk? If flying, TSA allows you to carry frozen and fresh breast milk through security, even if you’re not traveling with your baby. Use a well-insulated cooler with frozen ice packs to keep your milk at a safe temperature.

4. Breast Pads

Leaking happens—especially in the early days! Disposable or reusable breast pads absorb milk leaks, keeping your clothes dry.

5. Baby Bottle Labels

If you’re storing pumped milk or sending bottles to daycare, waterproof bottle labels make it easy to track dates, volume, and baby’s name.

6. Nursing Pillow for Pumping Support

A nursing pillow provides arm support while pumping, making sessions more comfortable. Some moms also find it helpful for hands-free pumping when paired with a pumping bra.

Frequently Asked Questions (FAQ)

2. Do I need a hands-free pumping bra?

While not a necessity, a hands-free bra makes pumping significantly easier, especially if you multitask or use a wearable pump.

3. How do I store breast milk while traveling?

Use an insulated cooler bag with frozen ice packs. If flying, TSA allows frozen breast milk in carry-ons—but check airline policies for additional details.

4. Can I pump directly into storage bags?

Yes! Some pumps connect directly to storage bags, reducing cleanup. Check if your pump brand offers compatible adapters.

Bottles are great for short-term use, while storage bags are best for freezing and saving space.
