I love our tots. I have so much more fun with them than I had with previous Sims games. As they gain skills, new options unlock, like new socials, better movements, and sleeping through the night better. I love my wild toddler who strips and runs around. I love the “Know what? Chicken butt!” joke and the moodlets they get. I think they redeemed themselves for not including toddlers in the first place. In a previous Sim game, I was told they could climb out of their crib on their own if they had something like a trait or body skill? Can’t remember- all I know is that happened ONCE in my game, they were usually just more of a pain than babies were, they had like 3 toys, and less to do with them.
I really don’t think they need to add another life stage here, I was thinking of styling my kids differently in the beginning of their child stage and giving them more of a tween vibe as they approach teenage years, this seems to make sense as they develop.
If they were to add a life stage, if anything, I think they should add the “middle aged” group back again.
