How to Increase Milk Supply: What Actually Works (And What Doesn't)

Supply anxiety is one of the most common concerns I hear from breastfeeding parents. The internet is full of conflicting advice — lactation cookies, supplements, power pumping schedules, galactagogues you can't pronounce. Let's cut through the noise with what the evidence actually supports.

First: Are You Actually Low Supply?

Most parents who worry about low supply actually have adequate supply. Before trying to increase your supply, check these markers:

• Diapers: By day 5, your baby should have 6+ wet diapers and 3+ dirty diapers per day
• Weight: Your baby should regain birth weight by 10–14 days
• Feeding: Your baby feeds 8–12 times in 24 hours and seems satisfied after most feeds
• Sound: You can hear swallowing during feeds

If these are all checking out, your supply is likely fine — even if it doesn't feel that way.

What Actually Works

1. Feed More Often

Supply is driven by demand. The single most effective way to increase supply is to put baby to breast more frequently. Every 2–3 hours, including at least once overnight.

2. Ensure Effective Milk Removal

A deep, pain-free latch that allows your baby to transfer milk efficiently is more important than any supplement. If you're experiencing pain or your baby seems to struggle at the breast, work with an IBCLC on latch and positioning.

3. Pump After Feeds

Adding a 10–15 minute pump session after 2–3 feeds per day sends additional demand signals. Don't be discouraged by small pump output — the signal matters more than the volume.

4. Skin-to-Skin Contact

Kangaroo care triggers oxytocin release, which supports letdown and milk production. Spend time skin-to-skin with your baby, especially during feeds.

What the Evidence Doesn't Support

• Lactation cookies and teas: No clinical evidence of efficacy. They won't hurt, but don't rely on them.
• Fenugreek: Mixed evidence at best, can cause GI issues in both parent and baby, and may actually decrease supply in some people.
• Drinking extra water beyond thirst: Staying hydrated is important, but over-hydrating doesn't increase supply.

When to Get Help

If you've tried increasing frequency and ensuring effective transfer for a week and you're still concerned, it's time for a clinical assessment. An IBCLC can evaluate latch, do a weighted feed, and rule out underlying causes.
