Getting the right nipple shield size is crucial for comfortable and effective pumping. Here's your step-by-step guide to finding your perfect fit.
What You'll Need
- A ruler or measuring tape (millimeters preferred) - or try our measuring card for easier sizing
- A mirror for better visibility

- Good lighting
Step-by-Step Measuring Instructions
1. Measure Your Nipple Diameter - Measure across the base of your nipple (not the areola) at its widest point. This should be done when your nipple is at rest, not erect.
2. Add 2-4mm for Comfort - Your nipple shield should be 2-4mm larger than your nipple diameter to allow for comfortable movement and prevent friction.

Wearable Breast Pump — Hands-Free, Heating & App-Controlled
This Pump is built for real life. Slip it in, connect via Bluetooth, and pump hands-free — whether you're at your desk, on the school run, or winding down at home. With three intelligent modes, a built-in heating function, and 9 adjustable suction levels, every session is tailored to you.
🔥 Why Heating Changes Everything
Most wearable pumps focus on suction alone. This pump goes further. Its built-in heating mode gently warms the flange before and during pumping — and that warmth makes a real difference.
Heat is widely recognised by lactation consultants as one of the most effective ways to support let-down. Warmth helps relax the breast tissue, encourages the let-down reflex, and can significantly improve milk flow — especially in the early weeks when feeding is still being established, or when stress and tension are making let-down harder to trigger.
For mums who struggle with slow let-down, pumping discomfort, or low output, the heating mode offers something most pumps simply don’t: a gentler, more natural pumping experience that works with your body, not against it.
- Encourages faster let-down — less waiting, more flow
- Reduces pumping discomfort — warmth relaxes tissue for a more comfortable session
- Supports milk output — particularly helpful in the early days or during stressful periods
- Use it your way — run heating alone, or combine it with Massage or Expression mode

- How do I wash these? All parts except the motor should be washed in warm soapy water after each use and sterilized once a day.
