Whether you’re a first-time parent or a seasoned pro, these tips will help you maximize your pumping sessions and keep your milk safe. We’ll also highlight how products like the TROVE Silicone Breast Pump and the FROSH Portable Milk Chiller can simplify your routine.

What Is a Silicone Breast Pump with Plugs?

A silicone breast pump is a soft, flexible device made from food-grade silicone that uses suction to express milk. Unlike traditional electric pumps, it is completely manual and relies on the natural letdown reflex. The pump fits over your breast and creates a gentle vacuum when you squeeze the bulb or body. Many models come with plugs that seal the opening, allowing you to store milk directly in the pump or transport it without transferring to a separate container.

The TROVE Silicone Breast Pump is a popular example, offering a 2-pump pack with plugs and a travel storage pouch. This design makes it easy to pump on one side while nursing on the other, collect letdown, or build a small stash throughout the day. The plugs are particularly useful for parents who want to combine milk from multiple sessions or simply need a spill-proof option for on-the-go use.

• Soft silicone conforms to your breast shape for a comfortable seal.
• Plugs allow you to close the pump and store milk in the fridge or cooler.
• No cords, batteries, or complex parts—just simple, quiet pumping.

Step 1: Prepare Your Pump and Workspace

Before your first use, wash all pump parts in warm, soapy water and rinse thoroughly. Silicone is non-porous and easy to clean, but it can attract lint or dust, so dry with a lint-free cloth. Assemble the pump by ensuring the bulb or body is attached securely, and check that the plug fits snugly in the opening. Have a clean surface, such as a sanitized tray or a clean towel, to place the pump during setup.

If you plan to pump directly into a storage container, consider using the FROSH Portable Milk Chiller to keep expressed milk cold right away. The FROSH chiller can maintain a safe temperature for hours, making it ideal for parents who pump away from home. Position yourself comfortably—sitting upright with good back support helps milk flow more easily.

• Sanitize pump parts weekly by boiling for 5 minutes or using a steam sterilizer.
• Keep extra plugs handy in case one gets misplaced or damaged.

Step 2: Position the Pump Correctly

Center the pump over your nipple, ensuring the flange (the cup that covers the breast) creates a complete seal. Gently press the pump against your breast, then squeeze the bulb or body to expel air. Release to create suction. You should feel a gentle pull, not pain. If the pump slips or loses suction, reposition and try again. The silicone material should conform to your breast without leaving marks.

For hands-free use, the pump can be held in place by a well-fitting nursing bra or a pumping bra. Some parents find that leaning forward slightly helps the pump stay in position. Once the suction is established, you can move around, type on a keyboard, or even lie back slightly. The quiet operation means you can pump during a meeting or while your baby naps without disruption.

• Warm compresses or gentle breast massage before pumping can boost letdown.
• If you experience discomfort, reduce suction by pressing the pump less firmly.

Step 3: Pump and Collect Milk

Let the pump do the work. The suction will naturally draw milk into the collection area. You may see drops or a steady stream. Pump for 10–15 minutes per side, or until flow slows. If you’re using the TROVE pump, the transparent silicone allows you to monitor milk volume. When finished, carefully release the suction by pressing the tab or lifting the edge of the pump.

Immediately insert the plug to seal the pump. This prevents spills and keeps milk fresh. If you’re combining milk from multiple sessions, cool the first batch in the fridge before adding fresh milk. The plugs make it easy to store the pump itself as a container—simply label with the date and time. For longer storage, transfer milk to CACHE Glass Storage Bottles, which are designed to preserve milk quality.

• Never add warm milk to already-cooled milk to avoid bacterial growth.
• Use a permanent marker on the plug or a sticker to date your milk.

Step 4: Clean and Store After Use

Disassemble the pump immediately after use. Rinse with cool water to remove milk residue, then wash with hot, soapy water. Silicone can retain odors, so a thorough rinse is important. Allow parts to air dry completely on a clean drying rack. The LAWN Drying Rack is an excellent choice because its angled branches allow air to circulate inside the pump and plugs, preventing mold.

Store clean, dry parts in a sealed container or the included travel pouch. Avoid storing silicone near heat sources or direct sunlight, as prolonged exposure can degrade the material. With proper care, a silicone breast pump can last for months or even through multiple children. Replace the pump if you notice cracks, tears, or persistent odors that don’t wash out.

• Use a dedicated bottle brush, like the MOD Bottle Cleaning Replacement Brush Set, to reach inside the pump.
• Boil silicone parts once a month to deep-clean and remove any buildup.

Tips for Maximizing Milk Collection with Plugs

Plugs are more than just caps—they help you manage your milk stash efficiently. Use them to seal the pump when you’re done, then place the entire pump in the fridge or a cooler. This reduces the need for multiple containers and minimizes handling. The TROVE pump’s design includes a secure plug that won’t pop off accidentally, even when jostled in a diaper bag.

If you’re pumping on the go, pair your silicone pump with the FROSH Portable Milk Chiller to keep milk cold for up to 8 hours. Simply seal the pump with the plug, place it inside the chiller, and you’re set. This combination is perfect for road trips, workdays, or visits to family. Remember to use milk within 4 days if refrigerated, or freeze it for longer storage.

• Practice using the plug one-handed—it’s easier once you get the hang of it.
• Keep a spare plug in your diaper bag in case you lose one.

Using a silicone breast pump with plugs is a simple, effective way to collect milk without the hassle of cords or electricity. With the right technique and accessories like the TROVE Silicone Breast Pump and the FROSH Portable Milk Chiller, you can pump confidently anywhere.
