Breast pumps: which type, when you actually need one, and how to use it

Plenty of mothers never need a pump. For the ones who do — returning to work, a preterm baby, supply problems — the right type saves hours.
Do you need one
You probably do if: you are returning to work and want to keep breastfeeding, your baby is preterm or in the NICU and cannot feed directly yet, you are building supply on medical advice, or you need someone else to feed the baby regularly.
You probably do not if: your baby feeds well directly, you are at home, and you only want an occasional bottle — hand expression covers that, costs nothing, and every mother should learn it anyway.
Do not buy one in pregnancy 'just in case'. Wait and see what your situation actually needs; the money is often better spent on a lactation consultation.
The types
Hand expression: free, always available, and genuinely effective once learnt. Ask the hospital's lactation counsellor to teach you before discharge.
Manual pump: inexpensive, quiet, portable, no power needed — which matters in a country with power cuts. Best for occasional use; tiring for daily pumping.
Single electric: mid-priced, good for regular use, one side at a time.
Double electric: expresses both sides at once, halves the time, and is what makes pumping at work sustainable. The right choice if you will pump daily for months.
Hospital-grade rental: strongest suction and best for establishing supply with a preterm baby or serious supply problems. Rent rather than buy — many Indian hospitals and lactation services offer this.
Check before buying: can you get replacement valves and membranes locally, is the flange the right size for you (the wrong size hurts and reduces output), and does it run on battery for power cuts.
Using it well
Start expressing two to three weeks before returning to work, once a day after a morning feed, when supply is highest. A stock of a few days' feeds is plenty; freezers full of milk are not necessary.
At work, express roughly every three to four hours to protect supply. Ask for a private space — not a toilet — and use the nursing breaks the Maternity Benefit Act provides.
Wash hands, sterilise parts for the first year, and never leave assembled wet parts to sit. Warm compresses, gentle massage and looking at a photo of the baby all genuinely improve let-down.
Storage: roughly four hours at room temperature, four days in the back of a fridge, and several months in a deep freezer. Label with the date, thaw in the fridge or warm water, never in a microwave, and do not refreeze thawed milk.
When to see a doctor
See a doctor or lactation consultant for: pain while pumping (usually the wrong flange size or too high a suction), cracked or bleeding nipples, a hard red painful area with fever (mastitis, which needs treatment and continued feeding), or a sharp fall in output.
Also seek help if you are pumping because the baby is not gaining weight — that needs assessment rather than more pumping.

Frequently asked questions
How much milk should I get in one session?
Anywhere from 30 to 120 ml across both sides is common, and output says little about your actual supply — babies are far more efficient than pumps. Judge supply by the baby's nappies and weight, not the bottle.
Can I mix milk from different sessions?
Yes, if both are chilled first to the same temperature before combining. Do not add warm fresh milk to already-cold milk.
Is second-hand a false economy?
Buy new or rent hospital-grade. Only closed-system pumps can be shared safely, and most consumer pumps are open-system, where milk can enter the motor.
My milk looks watery and blue-tinged.
Normal. Foremilk looks thin and bluish; the fattier hindmilk comes later in the session, and stored milk separates into layers. Swirl gently rather than shaking.

Every clinical figure on this page is taken from the guidelines below. Where our numbers and your doctor's differ, ask which guideline they follow.
- WHO. Infant and young child feeding: Model Chapter for textbooks for medical students and allied health professionals (2009)Supports the recommendation that hand expression is a valid and effective technique every mother should learn, and that breastfeeding should continue even when a baby cannot feed directly (as with preterm or NICU infants).
- WHO. Guideline: protecting, promoting and supporting breastfeeding in facilities providing maternity and newborn services (2017)Supports the claim that mothers of preterm or hospitalised infants should establish supply using expression (hand or pump) and that lactation support should be provided before hospital discharge.
- NHS. Expressing and storing breast milk (2023)Supports the storage guidelines (approximately four hours at room temperature, four days at the back of the fridge, several months in a deep freezer), the instruction never to thaw in a microwave, not to refreeze thawed milk, and the advice to chill milk before combining sessions.
- NICE. Postnatal care (NG194) (2021)Supports the recommendation that women returning to work who wish to continue breastfeeding should receive support with expressing, and that pain while breastfeeding or pumping (including cracked nipples and mastitis with fever) warrants prompt clinical assessment.
