When Should I Start Pumping — and How Much Do I Really Need? by Shannon Pratten, RN, IBCLC & Founder of Milk Drunk Club

Pumping can feel confusing fast — how soon to start, how often to pump, and whether you need a freezer stash “just in case.” In this post, NICU RN and IBCLC Shannon Pratten breaks down when pumping is actually needed, how much milk babies truly require, and why more pumping isn’t always better. You’ll learn how to avoid common mistakes that quietly sabotage supply, how to pump without throwing off your body’s rhythm, and how to protect your milk supply with calm, preventative guidance instead of panic.

Somewhere between your second pediatrician visit and your first Google spiral, you probably asked yourself:

“Should I be pumping already?”
“Am I supposed to have a freezer stash?”
“How much milk should I even be getting?”

Let me say this clearly, loudly, and lovingly:

You do not need a freezer full of milk to be a good breastfeeding mother.

Let’s break this down before the pump takes over your life.


First Things First: Pumping Is a Tool — Not a Requirement

If your baby is nursing well, gaining weight, and you’re together full-time in the early weeks, pumping is optional, not mandatory.

Breastfeeding itself is the most efficient way to:

  • Build supply

  • Regulate hormones

  • Establish the milk-making rhythm

Pumping too early, too often, or “just in case” can actually create problems — oversupply, engorgement, nipple pain, and a whole lot of unnecessary stress.

Yes, I said it. Sometimes more pumping is not better.


So… When Should You Start Pumping?

Here are the most common and appropriate reasons to introduce pumping:

✔ You’ll be returning to work or school
Most moms do best starting 2–4 weeks before returning, not at 2 weeks postpartum with no plan.

✔ You’re separated from your baby
NICU stay, medical separation, or missed feeds = pump to replace those sessions.

✔ Baby isn’t transferring milk efficiently
Temporary pumping may be needed while you work on latch, oral function, or stamina.

✔ You want one bottle a day (eventually)
Cool. We just do this strategically, not chaotically.


How Much Milk Do You Actually Need?

Here’s where the internet has lied to you.

A full-time working breastfeeding parent usually needs:

  • 1–1.5 ounces per hour of separation

  • About 3–4 ounces per feeding, not increasing endlessly with age

Breastfed babies don’t require larger and larger volumes the way formula-fed babies do. Breast milk changes — the volume doesn’t need to.

That means a massive freezer stash is not necessary.

A small buffer stash (10–20 ounces total) is plenty for most families.

Read that again. Then exhale.


When to Pump (Without Confusing Your Body)

The golden rule:

If baby gets a bottle, your body needs a signal.

That signal = pumping around the same time.

Helpful strategies:

  • Pump after one morning feed (when supply is highest)

  • Replace a missed nursing session with a pump

  • Avoid pumping right before feeds in the early weeks unless guided

Your body is listening. Be clear with the message.

 


The Pump Output Trap

Let’s clear this up once and for all:

Your pump is not a measure of your worth, your supply, or your success.

Some moms pump 6 ounces.
Some pump 1 ounce.
Both can have thriving, exclusively breastfed babies.

Pump output depends on:

  • Pump quality and fit

  • Time of day

  • Stress and fatigue

  • Your letdown reflex

Your baby ≠ your pump.


A Gentle Word About Oversupply

More milk sounds great — until it’s not.

Oversupply can cause:

  • Engorgement and pain

  • Plugged ducts and mastitis

  • Fast letdown that frustrates baby

  • Feeding that feels chaotic instead of calm

If you’re pumping “just to be safe,” check in with an IBCLC. We can help you build functional supply, not survival-mode milk production.


The Milk Drunk Truth

Pumping should support breastfeeding — not replace your instincts.

You don’t need a freezer stash worthy of a dairy farm.
You need:

  • A baby who feeds well

  • A body that’s listened to

  • A plan that fits your life

Milk-making is about communication, not accumulation.

And if pumping feels confusing? You don’t have to figure it out alone.

 

Want a Clear Plan to Protect Your Milk Supply?

If pumping has you second-guessing everything — how often, how much, or whether you’re doing it “right” — you don’t need more rules. You need clarity.

I created How to Protect Your Milk Supply for mothers who want calm, preventative guidance, not panic-driven pumping schedules or freezer-stash pressure. This guide walks you through how milk supply actually works, how to avoid the most common mistakes that quietly sabotage it, and how to support your body whether you’re nursing, pumping, returning to work, or doing a mix of everything.

It’s the exact framework I use with my private clients — simplified, reassuring, and grounded in physiology (not fear).
