Pumping Schedule and Milk Storage

There is no published pumping schedule, because the NHS's answer to how often to express is that it depends on why you are expressing. It names five reasons — being away from your baby, engorgement, a baby who cannot latch or suck well, sharing feeds with a partner, and boosting supply — and those five do not share a week. What is published precisely is the half of this subject the timetables bury: how long expressed milk keeps, and where.

So the storage comes first here, because it is the part with numbers behind it. The shape of a week comes after, described as what people do rather than as instruction, because that is all anybody can honestly call it.

Storage, which is the part that is measured

Expressed milk goes into a sterilised container or a breast milk storage bag, and then it keeps for:

• Up to 8 days at 4C or lower in the fridge. If yours runs warmer than that, or you do not know what it runs at, use the milk within 3 days.
• 2 weeks in the ice compartment of a fridge.
• Up to 6 months in a freezer at -18C or lower.
• Up to 24 hours in a cool bag with ice packs, for milk that has already been cooled in the fridge.

Frozen milk is defrosted slowly in the fridge. Milk that has been defrosted is never re-frozen. Once she has drunk from a bottle, that bottle is used within an hour and the rest goes. And nothing goes in a microwave — not to warm it, not to defrost it — because a microwave leaves hot spots that burn a baby's mouth.

Those are the only firm figures on this page, and it is worth noticing how far they are from a timetable. They tell you what a fridge can hold. They say nothing about what your morning should look like, and neither does anybody else.

The five reasons, and the week each one tends to make

Because the reason decides the frequency, the honest way to answer "how often" is to ask what the milk is for. What follows is the practical shape people describe for each of the five. It is unsourced — no publisher this site may cite prints a frequency for any of them — and it is here only so the timetables you have already read have something to sit against.

• Away from her. The pattern that fits is roughly whenever she would have fed, which is why work days tend to fall into breaks rather than into a clock. This is the one reason where the milk has a deadline attached: it has to be enough for the hours you are gone, on the day you are gone.
• Engorgement. Here expressing is for comfort rather than for a bottle, and a little to take the pressure off is a different act from emptying the breast. Full-blown engorgement, cracked skin or pain that is getting worse is a call to a midwife or health visitor rather than a pumping problem to solve alone.
• A baby who cannot latch or suck well. This is the reason with the least room in it, because the milk is the feed rather than a spare. It is also the reason that most needs a person watching: a feeding specialist can see the latch, and a page cannot.
• Sharing feeds. One bottle a day given by somebody else needs far less expressing than people expect, and it is usually one session that fits where the day allows rather than a slot defended at all costs.
• Boosting supply. The published mechanism is demand: milk is made as it is taken. What is not published is a protocol. No publisher this site may cite describes power pumping, names a session length, or prints a number of sessions a day, so this page does not either — and a supply worry belongs with a midwife, health visitor or breastfeeding specialist early rather than late.

The AAP's figure for a breastfed newborn is that they usually nurse every 2 hours, so 10 to 12 sessions in 24 hours is the norm. That is the baby at the breast, and turning it into a pumping rota is precisely the move this page refuses. How often to breastfeed a newborn covers what that figure does and does not mean, and cluster feeding covers the evenings when it stops looking like any number at all.

The mechanics, and where they come from

The claim this site registered from the NHS's expressing page carries two things: why you might express, and how to store what you get. Hand expressing, pump types, suction and sterilising are on the same page and are not in that claim, so take the paragraph below as a pointer to it rather than as a quotation of it.

Hands come first, and they are underrated. Hand expressing needs no pump, no electricity and nothing to sterilise beyond the container, which makes it the method that still works in a power cut, in a car, and at three in the morning when the pump parts are in the dishwasher. Pumps come in hand-worked and electric forms, and the choice between them is about how often and how fast rather than about quality of milk. Whatever you use, build the suction up slowly rather than starting at the top setting: expressing should not bruise you, and the nipple should not be caught or rubbed by the shield. Pain is a signal to stop and check the fit, not something to push through. Everything the milk touches is sterilised.

What the pump does not tell you

This is the sentence to take away if you take one: what comes out at the pump is not a measure of what she gets at the breast. A pump is a machine responding to suction, and a baby is not; a low-yield session is a fact about a morning and a device, not a verdict on you.

The checks the NHS does publish are about her rather than about a bottle. Feeds start with a few rapid sucks and settle into long rhythmic sucks and swallows you can see and hear. Her cheeks stay rounded rather than hollow. She comes off the breast on her own and seems content after most feeds, and the breast feels softer afterwards. Weight is gained steadily after the first 3 or 4 days, and losing some birth weight in those days is ordinary. From the fourth day there should be at least 2 soft yellow poos a day for the first few weeks, and from day 5 at least 6 heavy, wet nappies — diapers — every 24 hours.

If those signs are not there, or if you are worried at all, ask for help early rather than late: a midwife, a health visitor or a breastfeeding specialist. Early is the word the NHS uses, and it is the whole of the advice.

Writing it down without turning it into a target

A fortnight of notes is worth more than any schedule, because it shows your own pattern rather than somebody else's. What went in, what came out, roughly when — that is the evidence a health visitor can read in thirty seconds, and it beats trying to remember a week under four hours of sleep a night. The feeding chart printable and the day log are both one sheet, both filled in by hand, and neither works anything out for you, which is the point. If the milk is going into a bottle, paced bottle feeding covers the behaviours that are published about giving it.

One last thing about numbers on paper: they vary, day to day and side to side, and a chart of your own output is a record rather than a score. Nobody publishes what a session should yield, so there is nothing to fall short of.

This page is general information, not medical advice, and it cannot see your baby. Anything about her feeding, your supply, pain or weight gain belongs with your midwife, health visitor, GP or pediatrician.
