Before your first session
Wash your hands with soap and water before you touch any pump parts. Do this every time.
Read the instruction leaflet that came with your pump. The breast pumps available in Sri Lanka each come with a setup guide. Follow it to put the flange, valve, membrane, and collection bottle together in the right order. If the parts are not seated right, suction will not work.
Wash all parts that touch milk before first use. Hot soapy water and a rinse works. You do not need to sterilise for every session, but sterilising before first use helps.
Getting the flange size right
The flange is the funnel-shaped piece that sits against your breast. Size matters. A flange that is too small hurts. A flange that is too large loses suction.
Your nipple should move freely inside the flange tunnel during pumping. It should not rub the sides. There should not be a big gap around it.
Most pumps come with one standard flange size. If pumping hurts or your output is low after a few sessions, try a different size. Many brands sell sizes separately.
Starting the pump session
Sit comfortably. Hold the flange against your breast so it covers the nipple and areola. Press gently but firmly to get a seal. Do not press too hard. That blocks milk flow.
Start on the lowest suction setting. Most pumps have two phases. The first is a fast stimulation phase. The second is a slower expression phase. Let the stimulation phase run for one to two minutes before you switch to expression mode.
Do not start on maximum suction. More suction does not mean more milk. It means more pain. Start low. Increase suction little by little until you feel a strong but comfortable pull. That is your working setting.
Some mothers find it helps to look at a photo of their baby. The let-down reflex responds to emotional cues as well as physical stimulation.
What let-down feels like
Let-down is the reflex that releases milk. It can feel like tingling, gentle pressure, or warmth across the breast. Some mothers feel it clearly. Others do not feel it at all. Both are normal.
Milk usually starts flowing within one to three minutes of starting. If nothing comes after five minutes, try massaging your breast gently while the pump runs.
How long each session should be
Most sessions run 15 to 20 minutes per breast. A double pump cuts that to 15 to 20 minutes total for both breasts at the same time.
Pump until milk flow slows to a drip or stops. Some mothers finish in 10 minutes. Others take 25. Your body sets the pace.
Do not pump for longer than 30 minutes per session. Prolonged pumping with low output causes discomfort without benefit.
How often to pump
If pumping exclusively, aim for every two to three hours during the day. Include one night session. This matches a newborn’s feeding frequency and helps build supply.
If supplementing direct feeding, once or twice a day builds a freezer stash.
Storing pumped milk
Label every bottle or bag with the date and time before you store it. Milk stored at room temperature (below 25°C) stays fresh for up to four hours. In a refrigerator, it keeps for up to four days. In a freezer, it keeps for up to six months.
Cool pumped milk in the fridge before you add it to frozen milk. Do not add warm milk directly to a frozen supply.
After the session
Remove the flanges. Pour milk from the collection bottles into labelled storage bags or bottles. Take the pump apart and rinse with cold water first. That removes milk residue. Then wash with hot soapy water. Dry with a paper towel or leave on a clean rack.
Do not leave unwashed pump parts sitting for hours. Milk residue builds up fast in warm weather.

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. Frequency matters more than strength at this stage. Consult your midwife or lactation consultant if output is very low.
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 the same time. Stop when milk flow slows to drops for about two minutes. Going longer rarely produces more milk once flow has slowed.
Does breast pumping hurt?
It should not. Mild pulling is normal. Sharp pain or pinching means the flange is the wrong size, suction is too high, or the flange is not centred correctly. Always start at 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. In a freezer for up to six months. Label every container with the date and time pumped. Use the oldest milk first.
