The Sims 4: 10 Expansion Packs Fans Demand
3. Domestic Bliss Expansion Pack
In the Domestic Bliss Expansion Pack, homebody Simmers would enjoy a lot more freedom around the home and with family.
It would include having pets and toddlers, there would be after-school activities for children and teens, and a lot more life goals - you'd be able to have sleepovers for children, pets can interact with the toddlers themselves, events would be added that families can join together (like a BBQ's or family reunions), and the family tree interface would return alongide hobbies and favourites.
This is probably the most realistic Expansion Pack that EA might actually add to the game in the near future.
