Learn how to set up and use the Cimilre S6 breast pump with our step-by-step guide, including tips on collection kits and storage bottles.
Quick answer
To get started with the Cimilre S6, assemble the collection kit, attach the bottles, and follow the simple on-screen prompts to choose your suction level and begin pumping.
Why Setup Matters for Comfort and Output
Taking a few extra minutes to assemble your Cimilre S6 correctly can make a big difference in both comfort and milk output. A poor seal or an incorrect shield size can reduce suction and lead to discomfort.
The Cimilre S6 uses GentleFlow Technology™ to provide a smooth, quiet pumping experience, but this only works when all parts fit together snugly. Check that the valves are seated firmly and the bottles are screwed on straight to avoid leaks.
Choosing the Right Shield Size
The Cimilre Collection Kit comes with breast shields in different sizes. Using the correct size is crucial for effective pumping. If the shield is too small, it can cause friction and pain; if too large, it may not stimulate efficiently.
Measure your nipple diameter before pumping and choose the shield that fits comfortably without excessive areola pull-in. Many moms find that a size change improves both comfort and output.
Step-by-Step Setup and Use
- Wash and sterilize all parts: Before first use, wash the collection kit, bottles, and valves in warm soapy water and sterilize according to the manufacturer's instructions. This prevents contamination and ensures hygiene. Check that all parts are completely dry before assembly to avoid moisture buildup.
- Assemble the collection kit: Attach the breast shield to the valve, then connect the valve to the bottle. Ensure the valve is pushed in firmly to create a good seal. If you have a spare kit, you can assemble both sides ahead of time. A loose valve is a common cause of weak suction—double-check the fit.
- Connect the tubing and power on: Insert the tubing into the connectors on the pump and the collection kit. Plug in the power adapter or insert batteries if applicable. Press the power button to turn on the pump. Make sure tubing is not kinked or pinched, as this can reduce suction.
- Position the shields and start pumping: Center each shield over your nipple and hold it in place. Start with a low suction level and gradually increase to a comfortable setting. The S6 offers precise control over suction levels, so adjust until you feel a gentle tug without pain. If pumping hurts, stop and recheck the shield size and suction level.
- Store your milk properly: Once you finish pumping, pour the milk into Cimilre Storage Bottles or another BPA-free container. Label with the date and time, then refrigerate or freeze. Remember that bottle nipples and caps are not included with the storage bottle set, so use the provided discs and covers. Always use milk within the recommended storage times to ensure safety.
