Your first week with the Zomee Fit

What your Zomee Fit includes

Your Zomee Fit includes two pump motors, one for each side. You can pump both sides at the same time or one side at a time.

The Zomee Fit includes three sizes: 25 mm breast shields and 17 and 21 mm inserts. Additional sizes available for free with Perfect Fit Promise™. An insert sits inside the breast shield and makes its tunnel smaller.

Your box also includes these parts and accessories:

• Two breast shield bodies, two diaphragms, and four duckbill valves
• Two milk collectors and two milk collector lids
• Two USB-C charging cables with adapter
• Two bra adjusters, a nipple ruler and guide, a cleaning brush, and a manual in English and Spanish

Before your first session

Three steps get your Zomee Fit ready:

1. Wash and sanitize the washable parts: Before first use, wash them in warm water with mild dish soap. Then submerge them in a pot of boiling water for 5 minutes, the boiling time the CDC recommends. Lift them out with tongs and let them air dry.
2. Charge both pump motors: Use the included USB-C charging cables and adapter, and charge for 2 hours before your first session.
3. Measure both nipples: Use the nipple ruler to measure the widest part of the tip of each nipple, not the base. Match each side to the closest size, and if you land exactly between two sizes, start with the smaller one. Measure even if you've pumped before, because your size can change between pregnancies.

How do I start my first session?

Once the parts are dry, put each pump together and place it inside your bra. For the best hands-free pumping, wear your Zomee Fit with our 2-in-1 Pumping Bra. Sit upright while you pump.

When the pump is running, check your fit. The tip of your nipple should feel comfortable and move freely, without rubbing, pinching, or pulling. If it rubs or pinches, try the next size up. If too much of your areola pulls into the tunnel, try the next size down.

A built-in timer tracks each session, and the pump shuts off on its own after 30 minutes. The fullness sensor detects when your milk collector is full to help prevent spills.

Which mode should I start in?

Start in Stimulation Mode. Its short, fast, gentle suction is similar to how a baby nurses and helps trigger let-down. The first time you turn on your Zomee Fit, it starts in Stimulation Mode and switches to Expression Mode after 2 minutes.

Expression Mode is slower, deeper, and stronger. Start it at the same suction level you used in Stimulation Mode, and pump for 8 to 10 minutes. To encourage a second let-down, switch to 2-Phase Mode, which moves from gentle, faster suction into a slower, deeper pull.

If you have flat or inverted nipples, start your session in the Zomee Fit's exclusive Nipple Correction Mode. It uses gentle suction to draw out your nipple and center it in the breast shield for a better seal.

Each mode has nine suction levels. Turn suction up slowly, and only to a level that feels comfortable. You should never feel pain while pumping.

What do I do after each session?

Twist each milk collector off the motor, then cap it with its lid or pour your milk into a storage bottle or bag. Our milk storage guidelines cover how long it keeps.

Wipe each pump motor clean, and never wash it. Milk damage is behind many Zomee Fit motors sent back to us as defective.

Hand wash the washable parts with warm water and mild dish soap, and let them air dry completely before you put the pump back together.

For extra germ removal, the CDC recommends sanitizing pump parts at least once daily, after you clean them. That matters most if your baby is less than 2 months old, was born prematurely, or has a weakened immune system. For older, healthy babies, the CDC says daily sanitizing may not be necessary if you clean the parts carefully after each use.

To sanitize, steam the parts in the microwave or a plug-in steam system, or boil them for 5 minutes, and check your manual first. If your manual says the parts are dishwasher-safe, the CDC says a dishwasher with hot water and a heated drying cycle, or a sanitizing setting, makes a separate sanitizing step unnecessary.

High heat can warp silicone parts and wear them out sooner, so if you sanitize daily, check your duckbill valves and diaphragms more often.

Common problems and fixes

Check these before you decide something is broken:

• The pump feels weak: On a new pump, it's usually flange size. Measure again and try another of the three sizes. If none feels right, The Mom Line™ can help you measure and request your size.
• The pump pauses itself: Bending over, a sensor that needs a wipe, or a white bra can trigger the fullness sensor. Press play to keep pumping, or hold the mode button until ON or OFF appears and choose OFF. With the sensor off, empty each milk collector before it fills.
• Suction fades over time: Duckbill valves stretch and diaphragms can tear with use. Replace both every 1 to 3 months, depending on how often you pump and how you clean them.
• The pump won't charge: Use only the included cables and adapter, and don't leave a motor on the charger for long stretches.
• Milk leaks: Check each part for tears or warping.
• An error code appears: This most often means milk damage in the motor. Call The Mom Line at 1-888-662-7159.

Where to get help

For free help getting started with your Zomee Fit, or for pump, sizing, parts, and support questions, call The Mom Line at 1-888-662-7159 from 9 AM to 5 PM ET, Monday to Friday. Real moms and certified lactation consultants answer it. If you think the motor or a part is defective, The Mom Line can start a warranty claim, and we usually ask for a short video of the problem.

For feeding or supply concerns, talk to a lactation consultant (IBCLC). For pain, fever, or questions about your baby's weight or diapers, call your provider.
