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

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_LetDown folder (with HL_LetDown.ts4script + HL_LetDown.package) into your Mods folder.
Make sure script mods are enabled in Game Options.
(Optional) Add the HL_Hucow folder 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.
