I loved that despite them not being that playable, you could do smt w them. I loved taking babies outside, attending events with them, visiting families w babies to 'show off' Etc. There was a ,Going crazy' Moodlet in Sims 3 that showed up when you were inside your house a lot, which would def appear if you had a baby in the Sims 4 Object form. I get that interacting with complete babies is stupid, but I loved when I could take them outside on a walk. Why? Becauss not controlling them makes sense only if you play as one sim in your household.
