Using an electric breast pump for the first time can feel a bit overwhelming. There are flanges, valves, tubes, and suction settings to get your head around. This guide breaks it down step by step so you can set up the pump, position it properly, choose the right suction, and know how long to pump.
Before your first session
Wash your hands well with soap and water before handling any pump parts. It sounds basic, but it matters every time.
Before your first use, read the leaflet that comes with your pump. The breast pumps available in Sri Lanka each include a setup guide. Follow it closely so the flange, valve, membrane, and collection bottle are assembled in the right order. If parts are not fitted properly, the suction will not work as it should.
Wash every part that will touch milk before using the pump for the first time. Hot soapy water and a good rinse are usually enough. You do not need to sterilise before every session, but sterilising before first use is recommended.
Getting the flange size right
The flange is the funnel-shaped piece that sits against your breast. Getting the size right makes a big difference. If it is too small, it can cause pain. If it is too large, suction becomes less effective.
During pumping, your nipple should move freely inside the tunnel. It should not rub against the sides, and there should not be a big gap around it.
Most pumps come with one standard flange size. If pumping feels painful or your output stays low after a few sessions, try a different size. Many pump brands sell extra sizes separately.
Starting the pump session
Get comfortable, then place the flange over your breast so it covers the nipple and areola. Hold it gently but firmly to create a seal. Do not press too hard, because that can restrict milk flow.
Always begin with the lowest suction setting. Most pumps use two phases: a faster stimulation phase first, then a slower expression phase. Let the stimulation phase run for one to two minutes before switching to expression mode.
Do not start on maximum suction. More suction does not mean more milk. It usually just means more pain. Start low, then increase gradually until the pull feels strong but still comfortable. That is your working setting.
Some mothers find it helpful to look at a photo of their baby. The let-down reflex can respond to emotional cues as well as physical stimulation.
What let-down feels like
Let-down is the reflex that releases milk. It may feel like tingling, gentle pressure, or warmth across the breast. Some mothers notice it clearly. Others do not feel it at all. Both are normal.
Milk usually starts flowing within one to three minutes after pumping begins. If nothing happens after about five minutes, try gently massaging your breast while the pump is running.
How long each session should be
Most sessions last 15 to 20 minutes per breast. If you are using a double pump, that usually means 15 to 20 minutes total for both breasts at the same time.
Pump until the milk flow slows to a drip or stops. Some mothers finish in 10 minutes. Others need 25. Your body will set the pace.
Try not to pump for longer than 30 minutes in a single session. Pumping for too long without much output can cause discomfort without adding much benefit.
How often to pump
If you are exclusively pumping, aim for every two to three hours during the day and include one night session. That pattern helps mimic a newborn’s feeding rhythm and supports supply.
If you are supplementing direct feeding, one or two pumping sessions a day can help build a freezer stash.
Storing pumped milk
Label every bottle or bag with the date and time before storing it. Milk stored at room temperature (below 25°C) stays fresh for up to four hours. In the fridge, it keeps for up to four days. In the freezer, it keeps for up to six months.
Cool pumped milk in the fridge before adding it to frozen milk. Do not pour warm milk straight into a frozen supply.
After the session
Remove the flanges and pour the milk from the collection bottles into labelled storage bags or bottles. Disassemble the pump parts and rinse them with cold water first to remove any milk residue. Then wash everything in hot soapy water. Dry with a paper towel or leave the parts on a clean drying rack.
Do not leave unwashed pump parts sitting around for hours. Milk residue builds up quickly, especially in warm weather.
When pumping is painful
A little discomfort in the first few sessions can happen while your body adjusts. But sharp pain, bruising, or cracked nipples are not normal. Check the flange size. Check the suction setting. If the pain does not settle, speak to a lactation consultant. Pumping through pain usually makes things worse.
After each session, proper cleaning keeps pump parts safe for your baby. See our breast pump cleaning guide for the full step-by-step.

Frequently Asked Questions
Can you use a breast pump in the first days after birth?
Yes, but start gently. In the first three days, milk has not come in yet — you are expressing colostrum, which comes in small amounts. Use the lowest suction setting. At this stage, frequency matters more than strength. If output is very low, check with your midwife or lactation consultant.
How long should a breast pump session last?
Most sessions take 15 to 20 minutes per breast. Double pumping takes the same time for both sides at once. Stop when milk flow slows to drops for about two minutes. Once the flow has slowed, going longer rarely helps.
Does breast pumping hurt?
It should not. Mild pulling is normal. Sharp pain or pinching usually means the flange is the wrong size, the suction is too high, or the flange is not centred properly. Always start on the lowest suction setting and centre your nipple in the tunnel before increasing power.
How should pumped breast milk be stored?
At room temperature for up to four hours, in the fridge for up to four days, in a cooler bag with ice for up to 24 hours, or in a freezer for up to six months. Label every container with the date and time pumped. Use the oldest milk first.
