THE FIRST FEEDS

Getting started with breastfeeding

How do I know feeding is going well?

Listen for swallowing and look at wet nappies and weight gain together. The amount you express with a pump is a separate measure.

If you’re concerned about feeding or growth, ask your midwife, health visitor or breastfeeding specialist for help early.

What are the early feeding cues?

Your baby may turn towards the breast, open their mouth or bring their hands to their mouth. Offering a feed before they become upset can make getting started easier.

What should I check if feeding hurts?

Get comfortable and hold your baby close, with their head and body aligned. Ask a breastfeeding professional to observe a feed if attachment is difficult or pain continues.

A ROUTINE THAT WORKS FOR YOU

Getting started with expressing

You can express by hand or with a pump. How often you express depends on why you’re doing it.

Before a first session, have washed hands, clean equipment, your fitting instructions and a suitable milk container ready.

An occasional bottle

START SMALL

How often to express depends on your feeding situation. For a plan that fits you and your baby, speak with a breastfeeding professional.

Ask about your routine

COMFORT STARTS WITH FIT

Find a comfortable fit.

A measurement is your starting point. How the pump feels in use matters too.

Measure the nipple itself, without including the areola.

Measure each side

Check the diameter at the nipple base. Each breast may need a different size.

Centre, then check

Align your nipple with the tunnel. Check that it moves freely and does not rub painfully.

Keep suction comfortable

Start low. If you notice pinching, swelling or pain, stop and reassess. 

If pumping hurts, stop and check your flange size; if pain continues, speak to your midwife or a lactation consultant.

Different pumps. Different fitting systems.

Use parts made for your model.

FROM PUMP TO NEXT FEED

Storing & using expressed milk

Label containers with the date, store in small amounts and keep milk cold when you take it out.

Freshly expressed milk · NHS UK guidance
Where Conditions How long
Fridge 4 °C or below, at the back Up to 8 days
Fridge Unsure of temperature, or 5–10 °C Within 3 days
Freezer −18 °C or below Up to 6 months
Cool bag Previously chilled milk, with ice packs Up to 24 hours

Thaw in the fridge or warm water. Use defrosted milk straight away and do not refreeze it. Once a feed has started, use the milk within one hour and discard what remains. Avoid microwaves and stovetops.

Lola&Lykke milk storage bags hold 150 ml and are single use. The adapter is model-specific and does not connect to every pump. Check the bag and adapter instructions.

For premature or unwell babies, follow your care team’s guidance. This page uses NHS UK guidance.

LET YOUR BABY SET THE PACE

Feeding expressed milk

Watch your baby’s cues and leave room for pauses. They do not need to finish every bottle.

Invite

Touch the teat to the upper lip and let your baby draw it in.

Slow the flow

Hold the bottle nearly horizontal, with a slight tilt.

Pause

Watch for a break or signs that your baby has had enough.

Check the teat flow

Teat suitability depends on how your baby feeds, not the age label alone. If feeds are difficult or you are concerned about coughing or swallowing, seek feeding support.

NaturalFlow bottles and teats have their own assembly and cleaning instructions. Check the parts before each use.

CHECK, THEN GET HELP

When something feels different

A small assembly check can help with equipment issues. Pain and feeding concerns need a different kind of support.

My pump’s suction has changed. What should I check?

Check the assembly against your model’s instructions. Inspect the valves, membranes and seals for wear or damage, and check that parts sit correctly. Use replacements made for your pump.

Find model-specific replacement parts
Why is milk leaking from my wearable pump?

For Bloome, check the seals, assembly and position inside your bra. Use and remove the pump upright, follow the filling limit and pour as shown in the instructions. Stop using damaged components.

Are collection cups the same as a pump?

MilkCatch+ collects leaking milk; it is not an active pump. Reusable nursing pads absorb leaks rather than storing milk. Change damp pads and follow their washing instructions.

MilkCatch+ handling & care
My breast is painful, hot or swollen. Where should I turn?

Get clinical advice for worsening symptoms or if you feel unwell. Stronger suction or extra pumping is not a treatment for breast inflammation. NHS advice is to avoid firm pressure and expressing more milk than your baby needs.
