I hear ya. I had autonomy off the other day on one of my saves, but that irritating autonomous "Check Toddler" action kept coming up even though autonomy was supposed to be OFF. You know what happens when "Check Toddler" pops in, right? Everything in the adult sim's que is canceled. Everything in the Toddler's que is canceled. The world stops for those two sims for that obnoxious autonomous action. It's super annoying, especially when you've got the parents and kids up and the parent is supposed to be getting ready for work and the Toddler is about to pee themself so you're getting them to the potty right away (you know, since they're lv. 3 potty trained and can go by themself now)...and, bam, the potty interaction drops, the parent's shower interaction drops...because "Check Toddler" just barged in uninvited. Oh, or when the kid is really low on hunger and you're just letting them get a plate from the counter since the highchair is glitchy and poorly implemented...and when the kid is halfway to the counter and the parent is supposed to be sitting down to eat, BAM! "Check Toddler" ruins everything again!!
I wish they'd scrap that interaction as an autonomous behavior entirely, because it is soooooo broken. Even worse that that autonomous water drinking nonsense...
