I’d like to see toddlers get whims to play or talk with each other, like they do with their parents and older siblings. I’d also like to see toddlers get the ability to “escape” from a high chair (maybe with a high level Movement or Thinking skill) - same goes for cribs, if we ever get those. It could negatively affect Manners, and parents would have the option to discipline them for it. (And it’d fix the problem of parents always leaving their kids in high chairs - I’ll admit I got this idea when the parents in one of my households AUTONOMOUSLY WENT TO BED with their kid still in a high chair...)
