Do your toddlers "make a mess" coooonstantly?!

This sounds like it could be a bug that came with the new patch. How is she not spending her time better, with all those skills and discipline attempts?

I don't really have any toddlers in my active saves right now, they all grew up, but I'm still seeing my kids make messes too. Probably not as much as what you're describing though. I wonder if there's a mod that stops this from being an autonomous action.
