The Flange FITS™ Guide is an evidence-based way of doing flange fitting, which was used in the first study that compared "standard" flange fitting sizes and recommendations to using "smaller" flanges along with the Flange FITS™ Guide recommendations. This study was published in the Journal of Human Lactation's OnlineFirst November 30, 2025 edition. Click here to read the study!
Reach out to us with questions via email at jeanette@babiesincommon.com.
Additionally, the study was published as an Open Access article-we had to pay a couple thousand dollars to make that happen (from our personal funds), so if you'd like to donate to help reimburse us for that, we'd greatly appreciate it-every little bit helps! Thanks! Click here to learn more!
