Product Description

Before measuring:

Make your nipples larger by stimulating them (do not skip this step).

Two ways to measure

By nipple ruler

1. Hold the ruler with 0 lined up with the edge of one side of your nipple.

2. One the other edge of your nipple is the number in millimetres of your nipple diameter.

3. Nipples are not always the same size. Measure each nipple individually since you may not get the same measurement on the left and right sides of your chest.

By circular guide

1. Place the nipple into the smallest hole you can comfortably fit into without forcing it.

2. Your nipple should fit completely inside the circle.

3. Make sure you can see your entire nipple inside the circle and right where it meets the areolar tissue.

4. The number in millimetres indicates your nipple diameter.

5. Don’t forget to measure each nipple individually since you may not get the same measurement on the left and right sides of your chest.

If you measure the diameter of your nipple before beginning to pump or before you have your baby, you will add 3-4 mm to the measurement you found for choosing the correct breast shield size. Adding 1-2mm on nipple diameter to determine breast shield size after pumping.

NOTE:
It's important to check your breast shield size regularly as breasts may change throughout pregnancy and your breastfeeding journey. Based on nipple elasticity, you may need to size down if you have elastic nipples, or size up if you have less elastic nipples. If you feel discomfort or experience consistently reduced volume, you may need to try different sizes.

Please consult with a lactation professional if you're experiencing nipple pain or damage.
