Washington State DOH – WIC Flange FITS™ Guide (adapted from IBCLC Jeanette Mesite Frem)

Find your best-fit hard plastic flange first; then try silicone flanges/inserts and compare comfort/output.

Academy of Breastfeeding Medicine (ABM) Clinical Protocol #36 (2022) – Mastitis spectrum

Notes that improper flange size and pump settings can cause nipple/areolar trauma; fit is part of management.

ABM Clinical Protocol #26 (2016) – Persistent pain with breastfeeding

Recommends observing pumping and correcting flange fit; over-suction/poor fit → pain/trauma.

Lactation Network (IBCLC-authored): How to master breast pump flange fit

Explains that correct fit avoids rubbing/friction and that areola should not be drawn into the tunnel.

PubMed (2025) – “Flange Size Matters: A Comparative Pilot Study …”

Supports individualized sizing; smaller, precise sizes can be used without compromising comfort/output.

How these support your two lines

Hard 2-Piece: “Rigid tunnel + close fit can help limit over-draw with elastic nipples.” → #1, #2, #3, #5 (fit first with hard flange; poor fit causes tissue draw/trauma; individualized sizing).

Soft Inserts: “Soft silicone cushions the tunnel, reducing friction and helping limit pull-through.” → #1, #4 (compare silicone for comfort; friction/rubbing guidance).
