Household continues without me playing it?

Under "Options" (upper right hand corner, looks like three dots), go to "Game Options" and then "Gameplay Options" (listed in a list on the left side). One of the options are "Auto-Age Unplayed Sims" The option is automatically checked. When the option is unchecked, households you aren't playing won't age automatically. Not sure if this would stop a sim from giving birth if they are pregnant, but it would stop the baby or parents from aging. 

Please mark this as an accepted solution if it solves this!

as an edit: yes, all households are living and growing and aging during gameplay. Don't see any way to change this besides the above option.

I set my options to age only when playing household and it is still happening  All my pregnant sims have the babis and name them without me playing or being able to choose the names.

There's no way to make it nessecarily "stop" EXACTLY, but what you CAN do is do "save as" the next time you play and create 2 different save files at the same point of time. Name one of them as yours and one of them as your husband's. Just... make sure you both play the right one, and save to the right one too xD (Although that's pretty easy)

You are replying to a 3.5 year old thread. It is unlikely that the OP still is monitoring this thread.

I'm blind and didn't notice the dates xD Sorry lol
