Reader Question:
“My baby is 13 days old, and I haven’t started making milk. My baby’s latch seems fine, but I don’t get any milk when I pump. Please help.”

First, take a deep breath. You’re not alone, and this is a common concern for new parents. Milk supply in the early days can feel like a mystery, especially when you’re not sure how much your baby is actually getting. Let’s break it down into five things you need to know about milk supply and how to navigate these early weeks.

1. The Pump Isn’t the Whole Picture

It’s easy to feel like your pump output defines your milk supply, but here’s the reality: your baby is the best indicator.

Gaining weight,
Producing enough wet and dirty diapers, and
Content after feeds.

…then your milk is likely flowing just fine. However, if your baby seems fussy, feeds frequently but doesn’t stay satisfied, and you’re struggling to pump much milk, it might be time to explore your supply further.

💡 Quick Tip: Most pumps come with flanges that are too large, which can affect output. A good fit can make a huge difference. If you haven’t sized your flanges or figured out your ideal fit, check out the free sizing guide at the end of this blog.

2. Frequent Milk Removal is Key

Your body is learning how much milk your baby needs, and removing milk regularly signals it to keep producing. Whether through feeding or pumping, consistent milk removal is crucial for establishing your supply.

The early weeks can feel like a full-time job. It’s normal for newborns to feed every 1.5–3 hours, which adds up to 8–10 feeds per day. This intense phase doesn’t last forever—by 3–4 weeks, most parents find a rhythm that feels more sustainable.

💡 Quick Tip: If you’re offering a bottle after nursing, pump for 5–10 minutes afterward to maintain supply. If your baby is content without a bottle, you don’t need to pump.

3. Pumping Patience Pays Off

In the early days, small amounts of pumped milk are normal. Milk supply often increases gradually over the first few weeks as your body adjusts.

Even if you’re not pumping much, the act of pumping signals your body to produce prolactin, the hormone needed for milk production. Think of pumping as a way to build a foundation—it’s about consistency, not immediate volume.

💡 Quick Tip: Milk production fluctuates throughout the day, so don’t stress if you pump more at some times than others. Regular milk removal is what matters most.

4. Pumping Isn’t Always Necessary

If your baby is latching well and feeding efficiently, you might not need to pump at all. Pumping is primarily useful in situations where:

Baby isn’t latching,
You’re supplementing, or
You’re at risk for low supply and want to boost production.

It’s a common misconception that “the more you pump, the more milk you’ll make.” While milk removal is essential, excessive pumping doesn’t always yield more milk. Instead, focus on effective milk removal to meet your baby’s needs.

💡 Quick Tip: Conditions like PCOS, gestational diabetes, or hypothyroidism can sometimes slow milk production. If any of these apply to you, monitor closely and don’t hesitate to seek support.

5. Seek Professional Support

A certified lactation consultant can make all the difference, helping you troubleshoot challenges and create a sustainable feeding plan. Whether you’re struggling with latch issues, pumping routines, or milk supply concerns, their guidance can set you on the right path.

Many lactation consultants now offer virtual support, making it easier than ever to access help. If you’re unsure where to start, reach out here, and I’ll help you connect with someone who can support you.

Final Thoughts

Worrying about milk supply is a common stress for new parents, but remember: every feeding journey is different. Whether you’re feeding at the breast/chest, pumping, or supplementing, what matters most is that you and your baby are thriving.

Take it one feed at a time. Latching is a learned skill, and you’re doing an incredible job.
