The Infant and Sibling Pose Pack captures the sweet and playful bond between infants and their older siblings. It’s one of my favorite Sims 4 sibling poses packs, and it contains eight unique poses featuring cute moments like piggyback rides and cuddles. You can use these poses to show the care that comes with being the older sibling. Or, capture the perfect family portrait and place it in your Sims 4 Family House. You can create a photo wall in the entryway or the living room to add a lived in feel to your household.
Follow these steps to install Infant and Sibling Pose Pack on your Sims 4 game:
Download the mod file from the link above. Sims 4 mods typically come as .package or .ts4script files.
Open your Sims 4 Mods folder. The default location is: Documents/Electronic Arts/The Sims 4/Mods
Place the downloaded file directly into the Mods folder. You can organize mods into subfolders up to one level deep.
Launch The Sims 4 and go to Game Options > Other. Make sure "Enable Custom Content and Mods" is checked.
Restart the game if it was already running. The mod should now appear in your game.
Important: Always back up your save files before installing new mods. After Sims 4 updates, mods may need to be re-downloaded or updated by the creator.
Platform
The Sims 4 (PC/Mac)
Pro tip: If a mod stops working after a game update, check the creator's page for an updated version. Broken mods can cause the game to behave unexpectedly.
