The game is adopting babies without me

Do you have any mods or CC (custom content)? Try taking that out.
See this for more information: [PLEASE READ] Usage of Mods and Custom Content 

Nope, no mods or CC.. Just the plain games - that's why I find it so weird as well.

I moved your post to the bug forum @JenAMM91

Are you playing rotationally or is this your active household ?

Did you ever use mods and remove them or never used them ?

I have around 5 different household I play actively, and I've never used mods of any kind.. Any other ideas? 🙂

So everytime you switch back to one household they have new babies ? Or when exactly does this happen ? When you start the game ?

It's like every other time when I start the game, so far it hasn't happen between switching households once I'm playing

EDIT: Someone just posted this: http://answers.ea.com/t5/The-Sims-4/Why-do-babies-appear-in-my-bassinet-The-Sims-4/m-p/5131744

Could that be your issue ?

If not, try below

Try resetting your user files as described in the factory reset described in this post: http://answers.ea.com/t5/The-Sims-4/FAQ-Troubleshooting-Steps-amp-Known-Issues/m-p/3621199

You won't loose anything. Just make sure to not delete any files  and make a backup.

Try on a new game with nothing added back first (start new game). If it works, put back your save game and try again. If it still works, you can start putting stuff back.

• Options.ini (or just re-set all your settings manually)
• Tray Folder
• Screenshots/Videos/Custom music
• Rest of the save games (leave out slot_00000001.save which is the autosave)
• Custom content like clothing, hair, skins, make up ....
• Mods (one by one, making sure they all still work)

The rest does not need putting back, cause they are mostly cache files that recreate or log files that are not needed for the game.

I'll test resetting the user files, and hope it helps.

Thanks for all the tips and help!

So you didn't by a bassinet through buydebug ?
