How to Choose the Right Breast Pump: A Complete Guide for New Moms

Knowing what to look for in your next (or first!) breast pump can feel overwhelming. But don’t worry mama—we’ve got you. With so many incredible brands and options to choose from, you’re sure to find the pump that works best for you, and we’re here to help.

What to Think About Before Choosing a Breast Pump

Let’s explore seven key questions to help guide your search. Afterward, you’ll have a better understanding of pump types, suction strength, and comfort features, helping you make the best decision for your feeding journey.

Do You Plan to Breastfeed Directly or Exclusively Pump?

If your baby will mostly nurse directly, you may only need to pump occasionally to store extra milk, relieve engorgement, or keep up your supply. In this case, a manual, standard, or wearable pump might be enough, depending on how frequently you plan to pump.

If you’re planning to exclusively pump and bottle-feed your expressed milk, a high-powered electric pump is often the best choice. These pumps are typically more efficient for regular, full milk expression.

Will You Be Separated from Your Baby Frequently or Occasionally?

Regular separation—like going back to work or school—means you’ll likely need a high-powered pump that offers efficiency, portability, and ideally, a rechargeable or battery-powered option for on-the-go pumping. Wearable pumps can be helpful for discreet pumping when you’re away from a private space.

Occasional separation—like short trips to appointments or outings—might only require a simple manual or standard electric pump, especially if it’s under three hours at a time.

Do You Know Your Flange Size?

Flange size matters for both comfort and milk output. Pumps usually come with several flange sizes, and you don’t necessarily need to know your exact size before purchasing. However, for the most accurate fit, measure your nipples a few weeks postpartum.

If your pump doesn’t come with a suitable flange, you can either buy the correct size or use a flange insert to make adjustments. If you’re unsure how to measure or select the right size, a lactation consultant can help guide you.

Do You Need Regular Strength, Hospital Strength, or Hospital-Grade Suction?

Most pumps marketed as “hospital strength” are actually intended for personal use, and there’s no universal standard behind the term. These pumps can be strong and efficient, but a higher suction level doesn’t always mean better results—and in some cases, it can cause discomfort.

Hospital-grade pumps, on the other hand, are designed for multiple users (with individual kits for hygiene) and are often recommended for moms experiencing supply issues. These are usually available for rent with medical authorization after birth.

Do You Want Independent Control of Speed and Suction?

Some electric pumps allow separate control of cycle speed (how many times the pump “sucks” per minute) and suction strength (how strong the suction is). This feature helps tailor the experience to your comfort level and needs—especially important for exclusive pumpers or working moms.

Manual and many wearable pumps often have a single adjustment that increases both speed and suction at the same time, offering less customization.

How Does Suction Strength Affect Pumping?

It’s easy to assume that stronger suction is better, but the most effective pumping happens when using your maximum comfortable vacuum. This means adjusting the suction to a level that feels strong enough without causing pain.

Suction strength is measured in mmHg (millimeters of mercury) and usually falls between 220–350 mmHg. But instead of focusing only on numbers, pay attention to how the pump feels and how well it works for your body.

How Does Pumping Rhythm Influence Milk Production?

Pumping cadence, or rhythm, mimics the way a baby naturally nurses. Pumps often start with quick, shallow suction to stimulate let-down, followed by deeper, slower suction to draw out milk.

Some pumps use advanced suction patterns that copy a baby’s feeding style—alternating between flutter sucking and deep rhythmic pulls. This can encourage multiple let-downs and improve milk flow.

If you’re having trouble with suction, double-check your flange fit. An improper fit can reduce efficiency and comfort. The size and shape of your nipple, areola, and breast fullness all affect how the flange should fit.

Essential Accessories for a Smooth Breast Pumping Journey

Breast pumping is a unique experience for every mom, and having the right accessories can make all the difference. Here’s a guide to some must-have items that can enhance comfort, efficiency, and peace of mind throughout your breastfeeding and pumping journey.

Breast Milk Storage Bags

While bottles are useful for immediate feeding, milk storage bags are ideal for safely storing and organizing expressed milk. These bags take up less freezer space, are easy to stack, and are less likely to leak or break. Most are pre-sterilized and disposable, which helps keep your milk safe from contamination.

Nursing Pads

Leaks are a normal part of breastfeeding, especially during unexpected letdowns. Nursing pads—either disposable or washable—fit inside your bra to provide discreet protection and absorb moisture. Having a stash on hand can help you stay dry and comfortable.

Nipple Cream and Shields

Breastfeeding can sometimes cause temporary nipple pain or discomfort. Nipple creams made with natural ingredients can soothe and protect sensitive skin. Nipple shields can help address challenges like latching issues, flat or inverted nipples, or strong letdowns. If you’re unsure whether you need them, speaking with a lactation consultant can be helpful.

Pumping Starter Kits

If you’re feeling overwhelmed by the number of products out there, consider a starter bundle. These typically include a mix of storage bags, milk collection containers, cleaning supplies, and travel accessories. These kits are designed to provide the basic tools needed to begin your pumping routine confidently.

Breast Pump Bags and Storage

Keeping everything organized is key, especially if you’re on the move. A dedicated breast pump bag can help you store your pump, bottles, chargers, and extra parts all in one place. Many moms also add a cooler bag and ice packs for transporting milk safely during travel or commutes.

Hands-Free Nursing Bras

Hands-free pumping bras can save time and make multitasking easier. These specially designed bras hold pump parts securely in place, giving you the freedom to move or get things done while expressing milk. Look for soft, stretchy materials that are both functional and comfortable.

Making the Right Choice for You

Every mom’s breastfeeding and pumping journey is different. Whether you’re exclusively pumping or combining it with breastfeeding, the key is finding what works for you. If you often pump in multiple locations, having a second pump may be worth the investment, although insurance typically covers only one per pregnancy.

If you have questions about your equipment or need help figuring out sizing or accessories, a consultation with a lactation expert can make a big difference—and may be covered by insurance. Take your time, explore your options, and choose tools that support your individual needs and goals.

You’ve got this, mama!
