Quick Answer
CaraCups let you pump hands-free by placing the collection cup inside your bra. Connect them to your Spectra breast pump tubing, position the cup securely, and pump as usual. After use, empty the milk into a storage container and clean all parts thoroughly.
What You Need Before You Start
Before using CaraCups, make sure you have a compatible breast pump — they work with all Spectra pumps and many other brands. You'll also need your pump tubing, a flange that fits your nipple size (CaraCups are sold with flange size options), and a clean, comfortable bra that holds the cups in place without being too tight.
Choosing the Right Flange Size
Proper flange fit is critical for comfort and milk output. CaraCups come in multiple flange sizes — measure your nipple diameter and select the size that allows your nipple to move freely in the tunnel without rubbing. A too-small flange can cause pain and reduced flow; a too-large flange may pull in areola tissue and lead to engorgement or low output.
Step-by-Step Guide to Using CaraCups
- Step 1: Attach the flange and tubing: Snap the correct-size flange onto the CaraCup body. Connect one end of your pump tubing to the backflow protector (if your pump uses one) and the other end to the port on the top of the CaraCup. Ensure the connection is snug but not forced. Common mistake: Forgetting the backflow protector can let milk enter the tubing. Always use it if your pump model requires one.
- Step 2: Position the cup in your bra: Place the assembled CaraCup inside your bra with the flange centered over your nipple. The cup should sit flat against your chest. Adjust your bra so it holds the cup firmly — the cup should not shift when you move your arms. Checkpoint: If the cup tilts or gaps, your bra may be too loose. A nursing bra or a snug sports bra works best.
- Step 3: Start pumping: Turn on your pump and begin with the let-down mode (faster, lighter suction) for about 2 minutes, then switch to expression mode. You can move around, type, or relax while the cups collect milk hands-free. Common mistake: Starting on too high a suction level can cause discomfort. Always begin low and increase gradually.
- Step 4: Remove and empty the cups: When finished, turn off the pump, carefully detach the tubing, and remove the cups from your bra. Pour the expressed milk into a storage bottle or bag. The wide opening of the CaraCup makes transferring milk easy and sanitary. Checkpoint: Do not tip the cup while removing it — hold it upright to avoid spills.
- Step 5: Clean all parts immediately: Disassemble the flange, cup, and any valves. Wash each part in warm soapy water, rinse thoroughly, and air-dry on a clean towel. Spectra recommends using a dedicated brush to clean the flange tunnel. Avoid abrasive scrubbers that can scratch the plastic. Common mistake: Leaving milk residue in the valve can reduce suction over time. Inspect the duckbill valve for cracks or wear and replace it if needed.
Product Facts
- CaraCups Wearable Milk Collection Hands-Free Inserts: CaraCups are lightweight, BPA/DEHP-free, operate on a true-closed system, and are compatible with all Spectra breast pumps and other brands. The closed system prevents milk from entering the tubing, keeping your pump motor clean and reducing the risk of contamination. Lightweight design means less tugging on your breasts during hands-free pumping.
