How to Increase Your Milk Supply — A Practical Guide for New Mums

Low milk supply is one of the most common concerns for breastfeeding and pumping mums. The good news is that in most cases, supply can be improved with the right approach. This guide covers the most effective, evidence-based strategies to help you produce more milk naturally and sustainably.

Understanding How Milk Supply Works

Breast milk operates on a simple supply-and-demand principle: the more milk is removed from the breast whether by your baby or a pump the more your body produces. This means the most powerful tool you have is frequency and effectiveness of milk removal.

1. Feed or Pump More Frequently

Aim to breastfeed or pump every 2–3 hours, including at least once overnight. Prolactin (the hormone that drives milk production) is highest between 1am and 5am, making night sessions particularly valuable for building supply.

If you're returning to work or away from your baby, a wearable breast pump makes it much easier to maintain pumping frequency throughout the day without interrupting your routine.

2. Ensure Effective Milk Removal

Frequency alone isn't enough — the breast needs to be well-drained at each session. Signs of effective feeding include your baby swallowing regularly and your breast feeling softer after a feed. If you're pumping, ensure your flange size is correct and your pump has adequate suction.

3. Try Power Pumping

Power pumping mimics a baby's cluster feeding and is one of the most effective techniques for boosting supply. Try this once a day for several days:

  • Pump for 20 minutes
  • Rest for 10 minutes
  • Pump for 10 minutes
  • Rest for 10 minutes
  • Pump for 10 minutes

A double electric or wearable pump makes power pumping much more manageable.

4. Stay Well Hydrated

Breast milk is approximately 90% water. Aim for at least 2–3 litres of fluid per day. Keep a large water bottle nearby during feeds and pumping sessions as a reminder.

5. Prioritise Nutrition

Breastfeeding requires an additional 400–500 calories per day. Focus on nutrient-dense foods including:

  • Oats — a well-known galactagogue (milk-boosting food)
  • Leafy greens — spinach, kale, and broccoli
  • Legumes — lentils, chickpeas, and beans
  • Nuts and seeds — especially almonds and flaxseed
  • Protein — eggs, chicken, fish, and tofu

6. Manage Stress Where Possible

Stress and anxiety can inhibit the let-down reflex, making it harder for milk to flow even when supply is adequate. Practical strategies include skin-to-skin contact with your baby before pumping, looking at photos or videos of your baby while pumping, and creating a calm, comfortable pumping environment.

7. Avoid Unnecessary Supplementation Early On

Introducing formula before supply is established can reduce the frequency of breast stimulation and inadvertently lower supply. If supplementation is medically necessary, discuss with your midwife or lactation consultant how to protect your supply at the same time.

8. Consider Galactagogues

Some mums find herbal supplements such as fenugreek, blessed thistle, or moringa helpful. However, evidence is mixed and some can have side effects. Always consult your midwife, GP, or a lactation consultant before starting any supplement.

9. Seek Support from a Lactation Consultant

If you've tried the above and supply remains a concern, an International Board Certified Lactation Consultant (IBCLC) can assess your baby's latch, your anatomy, and your pumping technique to identify any underlying issues. In NZ, your midwife or Plunket nurse can provide a referral.

Sample Daily Pumping Schedules

Consistency is key to building supply. Here are two sample schedules depending on your situation:

Time Stay-at-Home Mum Working Mum
6:00am Breastfeed or pump Breastfeed or pump
9:00am Breastfeed or pump Pump at work
12:00pm Breastfeed or pump Pump at work
3:00pm Breastfeed or pump Pump at work
6:00pm Breastfeed or pump Breastfeed
9:00pm Breastfeed or pump Breastfeed or pump
2:00am Breastfeed or pump Breastfeed or pump

A wearable breast pump is ideal for working mums — discreet, hands-free, and easy to use between meetings.

When to See a Doctor

While most supply concerns can be addressed with the strategies above, some cases have an underlying medical cause. See your GP or midwife if:

  • Your supply hasn't improved after 1–2 weeks of consistent effort
  • You have a history of thyroid conditions, PCOS, or hormonal imbalances
  • You've had breast surgery or significant breast trauma
  • Your baby is not gaining weight adequately
  • You experience pain, fever, or signs of mastitis

Early intervention makes a significant difference — don't hesitate to seek support.

How Pumping Supports Milk Supply

For mums who are exclusively pumping, returning to work, or supplementing feeds, a reliable pump is essential for maintaining supply. Pumping after breastfeeds (even for 5–10 minutes) sends an additional signal to your body to produce more milk.

Our range of wearable and electric breast pumps are designed to support effective, comfortable milk removal — whether you're at home, at work, or on the go. Contact our team if you need help choosing the right pump for your situation.

Frequently Asked Questions

How quickly can I increase my milk supply?

Most mums see a noticeable improvement within 3–5 days of increasing pumping or feeding frequency. Consistency is key supply responds to sustained demand over time.

Does drinking more water increase milk supply?

Staying well hydrated supports milk production, but drinking excess water beyond your thirst won't significantly increase supply on its own. Focus on overall hydration as part of a broader approach.

Can stress reduce milk supply?

Yes. Stress can inhibit the let-down reflex, making it harder for milk to flow. Managing stress and creating a calm feeding or pumping environment can make a real difference.

Is it too late to increase my milk supply?

It's rarely too late, though it becomes more challenging as time goes on. Many mums successfully increase supply weeks or even months into their breastfeeding journey with the right support.

Does pumping increase supply as well as breastfeeding?

Yes; pumping is an effective way to stimulate supply, particularly when combined with breastfeeding or used to replace feeds when you're away from your baby. A high-quality pump with the correct flange fit makes a significant difference to how effectively milk is removed.

What is a normal amount to pump?

Output varies widely between mums and sessions. In the early weeks, 15–30ml per session is common and normal. By 6–8 weeks, many mums pump 60–120ml per session. What matters most is your baby's weight gain and nappy output, not the volume in the bottle.
