Quick answer

Center each Elvie Catch cup over your nipple, press the silicone rim flat against dry skin, and check that the cup sits inside your bra without folding. If leaking continues, the cause is usually fit, saturation, or how you remove the cup — not the cup itself.

Placement: where the cup should actually sit

Elvie Catch is a pair of silicone milk collection cups (1 oz each) that sits inside your bra to catch let-down. The cup only works when its opening is centered directly over your nipple. If the opening shifts to the side, milk lands on the rim instead of inside the cup and wicks onto your bra.

To place it: hold the cup with the opening facing your breast, center it over the nipple, then fold your bra cup over it and press gently. The silicone should feel smooth against your skin, not bunched. If you feel a hard edge or a crease, lift the bra and reset the cup before you start moving.

Fit checks that prevent most leaks

The most common cause of an Elvie Catch leaking fix that fails is a cup that is too loose or too compressed. A bra that is too tight can crush the cup so it cannot hold milk; a bra that is too loose lets the cup slide off the nipple. Aim for a bra that holds the cup snugly without denting it.

Before you leave the house, do a two-minute check: press the cup against your breast and let go. It should stay in place on its own for a second. Then put your bra on and move your arms in a circle. If you feel the cup shift, adjust the bra band or try a different bra before trusting it for a full day.

Capacity and saturation: when the cup is working but full

Each Elvie Catch cup holds 1 oz. If you leak more than that between changes, the cup will overflow no matter how well it is placed. This is a capacity limit, not a placement problem. Empty the cups every few hours on heavy leak days, or keep a spare pair in your bag.

If you regularly fill both cups before lunch, a higher-capacity wearable milk collector may suit you better than Elvie Catch. Elvie Catch is designed for comfort and confidence on the go, not for all-day heavy output.

Removing and reusing without spills

Most leaks at the end of the day happen during removal. Before you pull the cup away, lean forward slightly and slide a finger under the rim to break the seal. Then lift the cup straight up and pour the milk into a storage bag or bottle. Tilting the cup sideways while it is still sealed against your breast is the fastest way to spill.

Wash the cups with warm soapy water after each use and let them air dry completely before the next wear. A damp rim can lose grip and slide, which feels like a leak even when the cup is intact.

Elvie Catch vs nursing pads: which one fits your day

Nursing pads absorb leaks; Elvie Catch collects milk so it can be saved. If your goal is to keep your bra dry with the least bulk, a disposable or washable pad is simpler. If your goal is to stop watching milk go to waste, Elvie Catch is the better fit — as long as you are comfortable emptying and rinsing the cups.

Some people use both: pads on light days, Elvie Catch on days when let-down is heavier or when they want to save every drop. There is no rule that says you have to pick one forever.

Leak diagnosis: symptom, cause, fix, stop point

  • Milk on your bra within an hour of wearing: The cup opening is probably not centered over your nipple, or the silicone rim is folded against your skin. Reset the cup centered, smooth the rim flat, and re-check after five minutes of movement.
  • Cup feels loose or slides when you move: Your bra is too loose or the cup is sitting too low in the cup of the bra. Try a snugger bra or reposition the cup higher. If it still slides, this cup may not match your bra shape.
  • Cup is full and overflowing by midday: You are producing more than 1 oz per side between changes, which exceeds the cup's capacity. Empty more often or switch to a higher-capacity collector. Stop forcing Elvie Catch past its 1 oz limit.
  • Leak happens only when you remove the cup: The seal is still active when you tilt or pull the cup away. Break the seal with a finger under the rim, lean forward, and lift straight up.
