Smart Electric Breast Pump
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.
Size Chart - Nipple Diameter & Recommended Shield Size
15-17mm - 19-21mm shield
18-20mm - 22-24mm shield
21-23mm - 25-27mm shield

Pump Anywhere—No Cords, No Outlets, No Sitting Still
The Problem: Traditional electric breast pumps chain you to a wall outlet with tubes and wires everywhere. You're stuck in one spot, can't move around, and definitely can't take it with you when you're out.
The Solution: The Tiny Bloom Smart Electric Breast Pump is completely cordless and rechargeable. Slip it in your bag, pump in the car, at your desk, or while walking around the house—no power outlet required, no tubes to tangle.
