The Youha Breast Pump Shields are replacement flanges (breast shields) for your pump, giving you a way to match the shield to your body so expressing feels more comfortable and your pump can work as intended. Finding the right size is one of the most useful adjustments you can make to your pumping setup — a shield that fits well helps the pump maintain a good seal, while one that's too big or too small can make sessions uncomfortable and less efficient.
They're available in five sizes — 21, 24, 27, 30 and 36 — and each purchase includes one pair, so you can pump on both sides. They're compatible with the Youha The ONE, the Double electric pump, and other bottle systems that take 24 mm breast shields.
Why fit matters
Shield size isn't reliably guessed from bra size or general assumption — it comes down to the fit around your nipple as you express. Too tight and it can rub; too loose and the seal struggles. Having the size options on hand means you can find the fit that keeps expressing comfortable, which in turn helps your pump hold its vacuum through a session.
Replacement guidance
Breast shields are part of your pump's regular wear-and-care routine. Youha recommends replacing this part every 6 months, so keeping a fresh pair in rotation helps keep your setup working consistently.
Pandylane Pro Tip
If you're between sizes or unsure, it's worth having more than one size to compare during a session — the most comfortable shield is usually the one that lets you express without pinching or excess movement, rather than simply the size you expected.
