Pump Sizing Kit FAQ: Get Your Flange Size Right

Measuring and fit questions

How do I measure my flange size at home?

The sizing kit includes a sizing tool and a Pump Sizing 101 guide to help you find your size. The supplied instructions say to measure your nipples either an hour before or an hour after nursing or pumping. That timing matters because your nipple size can change during and right after a session.

What does the Breast Pump Sizing Kit actually include?

It comes with 5 insert sets for inclusive sizing, a sizing tool to easily find your size, a Pump Sizing 101 guide, and access to support via a Sizing Specialist. The inserts are designed to help you dial in flange fit for comfort and milk output.

What are the signs I'm using the wrong flange size?

The supplied information does not list specific wrong-size symptoms. What it does say is that fit has a direct impact on comfort and output while pumping, and that if your flange still doesn't feel comfortable, you should experiment with the other inserts. It also notes that a snug but stretchy pumping bra matters. If comfort or output still seems off, book a session with a Sizing Specialist for additional support.

Can I use the inserts with any breast pump?

The supplied product record does not confirm compatibility with specific pump brands or models. Before ordering, check that the inserts fit your pump's flange, or ask a Sizing Specialist. Do not assume they will work with every pump.

Buying and support questions

Is the Breast Pump Sizing Kit worth buying if I already have a pump?

If your current flanges feel uncomfortable or you are unsure of your size, the kit gives you five insert sets, a sizing tool, and a guide in one purchase. The catalog price is USD 12.50, compared with a catalog comparison price of USD 24.99. The supplied record does not state which pumps the inserts fit, so confirm compatibility first.

What if I measure and the flange still doesn't feel right?

The supplied guidance is to experiment with the other inserts. It also suggests making sure you are wearing a snug but stretchy pumping bra. If you need more help, you can book a session with a Sizing Specialist.

Does the kit come with a warranty?

The supplied information lists a 2-year warranty on electric pumps and a 90-day warranty on accessories. It does not specify which category the sizing kit falls under, so check the accessory warranty terms before you rely on it.
