Pumping & Milk Supply: Expert Tips from Leanne Rzepa, RN BN IBCLC

Feeding looks different for every family — and that’s perfectly okay. Whether you’re exclusively pumping, combo feeding, or just starting to explore breastfeeding, we know how many questions can come up along the way.

To help, our collective expert Leanne Rzepa, RN BN IBCLC, answered some of the most common questions parents ask about pumping, milk supply, and all things feeding support.

Q: How do I know when to stop pumping?

A: Once your milk stops flowing, let the pump run for another two to three minutes on the stimulation or initiate setting.If there’s no milk flow after three minutes, it’s time to turn the pump off. That extra bit of time helps signal your body to keep producing milk and can support overall supply.

Q: Is there a better time to pump — daytime or nighttime?

A: Most of us tend to have more milk earlier in the day, so Leanne recommends pumping after early morning or late morning feeds. Babies often cluster feed in the late afternoon or evening, which can make it harder to fit in a pumping session.

Tip: Power pumping (short, frequent sessions) can be a great way to boost supply — and is most effective when done earlier in the day.

Q: My newborn only contact naps — how do I maximize pumping time?

A: You’re not alone! During those contact-nap phases, a hands-free or wearable pump can be a lifesaver. It allows you to continue expressing milk while keeping your little one close — no need to give up those cozy naps together.

Q: Should I snack before or during pumping?

A: Whenever it works for you! Your body needs about 500 additional calories per day while producing milk, so nourishment is key.

Reach for snacks that are:

  • High in protein, fiber, and healthy fats

  • Easy to eat one-handed (because… parenting)

Think: trail mix, Greek yogurt with fruit, avocado toast, or smoothies with nut butter and oats. Hydration helps, too!

Q: How can I increase my milk supply?

A: The best way to support milk supply is through optimized breastfeeding and consistent milk removal — either nursing or pumping after feeds to tell your body to make more milk.

You’ll also want to check for any underlying causes that can impact supply, such as:

  • PCOS (Polycystic Ovary Syndrome)

  • Low iron

  • Insufficient glandular tissue

  • Breast hypoplasia

Working with a lactation consultant can help you identify and address these factors.

Q: How can I increase my supply at six months postpartum?

A: Around six months, milk supply often changes — especially if your baby is eating solids or your period has returned. To give it a boost, try expressing milk after daytime feeds and once overnight.

Some parents also find goat’s rue (a herbal supplement) helpful, but always check with your healthcare provider before starting anything new.

Q: Can I pump out a clogged duct?

A: Yes — pumping can absolutely help! Combine it with gentle icing and light pressure over the clogged area. Avoid deep massage (it can cause bruising or irritation), and instead focus on gentle, consistent care until it clears.

Q: What’s the best manual pump?

A: Medela and Avent — both make great manual pumps that are simple, reliable, and affordable.

Q: What’s the best affordable pump for first-time parents?

A: Medela offers a range of pumps at different price points and comfort levels. Other pump brands Leanne loves include Spectra, Imani, and Baby Buddha — each with unique features depending on your needs.

Q: How can I tell if my milk flow is slowing down or stopping?

A: You’ll notice milk flow slows or stops, and that’s your sign to switch settings or finish the session. Letting the pump run for a few minutes after flow stops can encourage more letdowns — but if nothing happens after three minutes, you can safely turn it off.

Q: When’s the best time to power pump?

A: Power pumping works best earlier in the day when milk production is typically higher. Try it after a morning feed or during a consistent time each day to signal your body to make more milk.
