Why: Exclusive pumping allows babies to receive breast milk when direct nursing isn't possible. Supply follows demand.
How: Daily requirement = baby weight × 150-160 mL. Divide across sessions. More frequent emptying typically increases supply.

What is Exclusive Pumping?
Exclusive pumping (EP) is when a mother provides breast milk for her baby entirely through pumping rather than direct breastfeeding. This allows babies to receive all the benefits of breast milk while accommodating situations where direct nursing isn't possible or preferred.
Establishing (0-12 weeks)
- • 8-12 sessions per day
- • Every 2-3 hours including night
- • Building supply foundation
- • Don't skip MOTN pumps
Maintaining (12+ weeks)
- • 5-7 sessions typically
- • Supply is demand-driven
- • Can drop pumps carefully
- • More flexibility in schedule
Building Stash
- • Freeze excess milk
- • 3-day emergency supply goal
- • Rotate frozen milk (FIFO)
- • Label with date and amount
How to Pump Effectively
Pump Technique
- • Start with let-down mode (fast, light suction)
- • Switch to expression mode after let-down
- • Use highest comfortable suction level
- • Massage and compress during pumping
- • Pump until empty + 2 minutes
Equipment Care
- • Correct flange size is crucial
- • Replace membranes every 2-4 weeks
- • Replace valves every 2-3 months
- • Wash parts after each use (or fridge hack)
- • Sanitize daily
