I think babies having a bit more of a personality would be cool! Being able to change their outfits maybe be able to offer them like a dummy or comforters things like that. Having different style cots would be nice aswell previous sims had cool style cots for the babies, i know you can have ones from vampire pack but they are more like moses baskets, having a cot with the sides like old games. Feel like im rambling and not making much sense i apologise lol. Adding to your family is one of my favourite parts of sims so love this section.
