“My milk supply dropped…”
…or your body regulated
Around 11-14 weeks postpartum, milk production shifts from hormone-driven to supply-and-demand
It can feel like everything changed overnight
What regulation often looks like:
• Breasts feel softer
• Leaking slows or stops
• You’re not feeling full between feedings
• Less of that sweaty, engorged, sticky feeling
• Pump output may look different
• Baby may cluster feed again or seem unsettled
These are hormonal shifts into efficiency, not signs your milk is going away
What’s happening physiologically:
In the early weeks, hormones drive higher volume production and storage
That’s why breasts feel full, heavy, and leaky
As your body learns your baby’s needs, it adjusts:
• Extra blood and fluid are in the breast for the first few weeks to help push milk to the baby while they are learning to feed. This goes away and breasts feel soft
• Production responds more to milk removal
• Supply becomes tightly matched to your baby
This timing throws people off because this phase often overlaps with:
• A final early growth spurt
• Periods of cluster feeding
• Changes in sleep that can look like a regression
So you see more feeding + less fullness + more night waking
It’s easy to assume supply is dropping
What’s important to understand:
• Babies don’t keep increasing daily milk volumes for long. Once they reach 10-12 pounds, they need 25-30oz a day. And that’s what they need daily through the first birthday. Not gallons a day
• As a newborn, babies usually take 65-80% of the milk in the breast at any given feeding. There’s more milk always available for cluster feeds and growth spurts
• Growth continues, just at a slower, steadier rate
• Your body is matching that shift
What to watch instead:
• Diaper output
• Swallowing during feeds
• Growth patterns over time
• Overall feeding behavior
Soft breasts can still contain plenty of milk
Less leaking doesn’t mean less milk. It means more efficient milk production
This is milk supply regulation into the next stage of lactation and is expected
