About This File
LetDown adds a self-contained lactation system to The Sims 4: a Sim fills with milk over time, her body responds, and that milk becomes something you can express, sell, cook with, or drink.
How it works
- Get lactating. Order a Lactea Supplement from the mailbox (§15) and take it, or let it trigger automatically after giving birth. The Sim gains the Lactating trait and a fixed milk flavor.
- Fullness builds over time. As milk accumulates, moodlet buffs escalate through Filling Up → Swollen & Aching → Ready to Burst, and her breasts visibly swell with the fullness — easing back down once she's drained.
- Express the milk. Another Sim can Express Milk from a lactating Sim, producing a bottle in the inventory.
- Do something with it. Bottles come in five flavors (Strawberry, Vanilla, Banana, Chocolate, Natural). Sell them on the occult market (vampires pay a premium for chocolate, mermaids for strawberry…), cook them into a Milky Delight, or serve a glass straight from the fridge's Breast Milk menu and drink it for a flavor buff.
Features
- Time-based fullness loop with escalating moodlets
- Dynamic breast growth that scales with fullness
- Milk bottles (5 flavors), sellable and cookable
- Fridge "Breast Milk" serve-a-glass submenu
- Occult buyer market with flavor preferences
- Post-partum auto-activation
- WickedWhims integration (draining during tagged animations)
Companion mod — Hucow (early, in development)
There's an optional companion: Hucow (HL_Hucow), which requires LetDown. It's an early add-on that will keep growing over time. Right now it adds a custom "Lactation" need bar to the needs panel, so you can watch a Sim's fullness build at a glance. The full fantasy — an occult-style Sim that gradually transforms into a cow/hucow, with its own progression and traits — is planned for future updates and isn't in this build yet. Install LetDown first, then drop Hucow on top.
Requirements
- The Sims 4 (base game)
- WickedWhims — recommended. The body growth targets the nude body, and the mod hooks WW animations for draining.
- Hucow additionally requires LetDown installed.
Installation
- Unzip.
-
Drop the
HL_LetDownfolder (withHL_LetDown.ts4script+HL_LetDown.package) into yourModsfolder. - Make sure script mods are enabled in Game Options.
-
(Optional) Add the
HL_Hucowfolder the same way for the companion need bar.
Translations (community)
The mod ships in English. Translations work as drop-in language packs: download a HL_LetDown_Translation_<LANG>.package, place it next to the mod, and that language is used — remove it and it falls back to English.
Want to translate it to your language? Grab the translation template, open it in Sims 4 Studio (STBL / Translation tab), replace the English text with yours, and save. That file is the translation — share it for others to use.

Compatibility & notes
- Works alongside other lactation/body mods; the milk economy and buffs are self-contained.
- English only out of the box; other languages via the community packs above.

What's New in Version 0.2.5
Released
- The fridge's "Breast Milk" menu now works like any EA recipe: flavors you have no bottle for are greyed out, and pouring a glass actually consumes one bottle of that flavor. No more free glasses out of thin air.
- Bottles count whether they're in the Sim's inventory or in any fridge on the lot.
- Flavor buffs now always apply when you drink a glass. Before, if the mod couldn't find a matching bottle it silently skipped the buff.
- Cancel a glass halfway and the bottle goes back to your stock.
COOKING MILKY DELIGHT — FIXED
- You can finally cook it. The recipe shipped since v0.1 but was never attached to any menu, which is why nobody could find it. It now sits in the same fridge "Breast Milk" menu, and takes one Strawberry bottle.
UNDER THE HOOD
- The custom code that faked all of this was removed. The game handles it natively now, which means fewer moving parts and no more mismatch between what the menu offers and what you actually have.
NOTES
- Bottles must be in a fridge or in a Sim's inventory. The EA Drink Cooler has no storage of its own, so on a lot without a fridge every flavor will show as greyed out there.
- The bottle is consumed when the glass is served, not when it's drunk.
- Milky Delight is cooked, not poured: your Sim takes the ingredients from the fridge and prepares it on a counter, so the lot needs one.
