Facilitating Lactation Through Optimized Workflows - Evaluating the Efficiency of Pumping Protocols and Cellular Mechanisms of Milk Production (FLOW)

June 2, 2026 updated by: Casey Rosen-Carole, University of Rochester
The purpose of this study is to evaluate the effectiveness of two different breast pumping protocols in increasing milk production among lactating individuals diagnosed with primary low milk supply, and to investigate the associated molecular, hormonal, and inflammatory mechanisms driving milk output.

How is the study designed?

Design Details

  • Primary Purpose: Treatment
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Pumping 6-8 times a day (also known as triple-feeding protocol)
Other: Pumping frequency intervention
In this randomized clinical trial, we will evaluate whether a lower frequency of pumping (3-4 times/day) or no additional pumping recommendations can lead to higher compliance, an increase in milk production, and a longer duration of breastfeeding.
Experimental: Pumping 3-4 times a day (lower frequency of pumping)
Other: Pumping frequency intervention
In this randomized clinical trial, we will evaluate whether a lower frequency of pumping (3-4 times/day) or no additional pumping recommendations can lead to higher compliance, an increase in milk production, and a longer duration of breastfeeding.
Placebo Comparator: No additional pumping will be recommended (mothers can choose to pump as they desire)
Other: Pumping frequency intervention
In this randomized clinical trial, we will evaluate whether a lower frequency of pumping (3-4 times/day) or no additional pumping recommendations can lead to higher compliance, an increase in milk production, and a longer duration of breastfeeding.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Milk Production
Time Frame: 6 month follow-up
The study will measure milk production over 24 hours using a 24-hour test weighing (weighing infants before and after each feed) before and after the intervention.
