Leaking is not normal with Freemie Cups. This post covers why your cups might leak.
Although it’s rare, a defect can happen and your warranty covers any manufacturer defects that should arise within 60 days of purchase. After this, leaking is likely due to incorrect use or care of the product. This most often occurs when:
- The hard cup parts were not boiled for the recommended 10 minutes
- The parts were steamed (microwave bag, dishwasher, bottle sterilizer)
- Abrasives such as bottle brushes or scrub pads were used, or other damage has occurred
- The parts were stored in the fridge
Boiling the parts is important for two reasons:
- It sanitizes the cups before first use
- It helps mold the parts to each other making them airtight
You are welcome to boil the hard cup parts (cups, breast flanges and valve bases) as often as you’d like. Do not ever boil soft parts like duckbill valves, barriers, quick connectors, or tubing.

Correct, no steaming. Freemie parts are made from a lightweight medical grade and food safe plastic. This material is strong and durable and can withstand boiling water but is susceptible to damage from very high temperatures. Our cups can handle the temperatures water reaches at a boil, but steam can warp them causing them to leak.
Think of Freemie like your best bra. You wash it by hand. You’d never throw your best bra in with kitchen towels on a hot cycle, right? Or, think of how plastic can look after it’s been microwaved, held tomato soup, or comes out of the dishwasher cloudy — it’s just never quite the same again! The same is true for Freemie.
Think about it. Freemie is not your average pump solution. You wear it. It can’t leak. It really, really can’t leak. If you scrub the parts with a scratchy sponge or bottle brush with hard bristles, the parts get scratched. If you drop them on cement, they won’t crack but they can get scratched. If you wash them with other dishes and a fork gouges just one part, you have a scratch. What happens with scratches? They cause leaking. It’s called capillary action. Avoid it.
Yes, cold blows. Why can’t they go in the fridge? Because it is super important that they don’t leak. Freemie has special benefits, and special care. Don’t treat Freemie like bottles and horns. If you put the cups in the fridge you may have problems so don’t cold store.
