Going back to work is a big shift, and worrying about feeding on top of everything else is completely understandable. The good news: plenty of parents keep breastfeeding, pumping, or do a mix of both for as long as they choose. You don't need a perfect plan — just a workable one.

Start a few weeks before you go back

You don't need a giant freezer stash. A small buffer of 2–3 days' worth of feeds is plenty to start, and you can keep topping it up once you're back.

  • Begin pumping about 2–4 weeks before your return date.
  • A good time is in the morning, when supply tends to be highest — try pumping once after the first morning feed.
  • Add the milk you collect to your buffer gradually. Even 60–120 mL a day adds up quickly.

Pumping at work

Aim to pump roughly as often as your baby would normally feed — for most babies that's around every 3 hours, so two to three sessions across a standard workday.

  • Each session usually takes about 15–20 minutes.
  • Bring a cooler bag with an ice pack to store milk safely until you get home.
  • A photo or video of your baby, or a worn item of their clothing, can help your milk let down.
  • In Australia, breastfeeding is a protected attribute under the Sex Discrimination Act 1984, so it's unlawful for a workplace to treat you unfavourably for breastfeeding or expressing. Work health and safety law also supports a safe, private space, and the Fair Work Act lets you request flexible working arrangements. Many employers provide a private room and breaks — it's worth asking HR early.

If your supply dips after a busy day, don't panic. It's common and usually recovers with rest, hydration and a few extra feeds or pumps when you're together.

Storing milk safely

Storage times vary slightly by region, so use this as a general guide and follow your local health service if in doubt.

Where General guidance
Room temperature (≈26°C or below) Up to 4 hours
Insulated cooler with ice pack Up to 24 hours
Fridge (4°C or below) Up to 4 days
Freezer About 6 months (up to 12 in a deep freezer)
  • Label every container with the date.
  • Use the oldest milk first (first in, first out).
  • Thaw in the fridge or under cool, then warm, running water — never in the microwave, which heats unevenly and destroys some protective factors. The milk storage guide has the full details.
  • Don't refreeze milk once it's thawed.

Combination feeding is okay

Mixing breastmilk and formula — combination feeding — is a completely normal and valid choice, whether by necessity or preference. Many families land here, and your baby can absolutely thrive.

  • Introduce a bottle a week or two before you return so your baby (and their carer) can practise. Paced bottle feeding helps prevent overfeeding and keeps the experience calm.
  • If you're adding formula, follow the tin's instructions exactly and prepare it safely with freshly boiled, cooled water.
  • Your supply adjusts to demand, so any breastfeeds or pumps you keep up still matter.

A safety note for carers

One thing worth sharing firmly with anyone who looks after your baby: always place them on their back to sleep, day care included (Red Nose, AAP).

Whatever blend of breastfeeding, pumping and formula you choose, fed and loved is what matters. Be kind to yourself — you're doing a hard, generous thing.
