Using the right horn size for your nipples is key for your comfort and efficiency.
Our new wearable pump has a 24mm horn, and also comes with 13mm, 15mm, 17mm, 19mm and 21mm horn inserts and a handy measurement guide. Ready to measure? We've got you with a step-by-step guide.
Try starting with the horn or insert size closest to your nipple measurement. And consider trying the next size up or down, too.
Your pump shouldn't pinch, rub or cause any discomfort.
You've found your ‘sweet spot’ when you experience the most comfortable and consistent breast milk flow.
Your nipple rubs against the tunnel and none of your areola is pulled in.
More of your areola is sucked into the horn and may rub against the edge of the tunnel.
Your whole nipple fits comfortably without much (if any) of your areola entering the tunnel before you pump. While you express, only a little bit of your areola is pulled into the tunnel.

Centre of your nipple moves freely in and out of the tunnel.

Motion of expression is gentle and rhythmic.
Feels comfortable with no rubbing, redness, or pain.
Yields well-expressed breasts that feel softer and lighter after each session.
Pumping should feel steady and gentle. If there's sharp pain, ongoing tenderness, or any rubbing that leaves your skin sore afterwards, you may need to try a different horn size.

Experiment with your electric pump's settings to choose the right ones for you. Start low and work your way up a level each time, if the pace or pull of the suction is too intense, dial it back. What feels right for you can change from one session to the next.
By switching modes and adjusting suction levels, you can create a pattern that works best for your body.
