🌸 Understanding the Feedback Inhibitor of Lactation (FIL) 🌸
Did you know your breasts have a built-in supply & demand system? One key player is something called the Feedback Inhibitor of Lactation (FIL) — a protein in your milk that helps regulate how much milk your body makes. 👶🏻
✨ Here’s how it works:
When milk sits in the breast for too long, FIL builds up and sends a signal to slow down milk production. It’s your body’s way of saying, “There’s enough here for now!”
So if you’re trying to increase your milk supply, the key is to empty the breasts more often to keep that FIL from telling your body to make less.
💡 To support your supply:
✅ Nurse frequently, on demand
✅ Offer both breasts at each feed
✅ Pump in between feeds if needed
✅ Make sure baby is latching well and effectively removing milk
Your body is amazing — and it’s always listening. 🫶
