I've been seeing routing issues related to Baby Care actions for a while, and they're still happening in the latest update (1.125.59.1230). I'm on a Mac, with a vanilla game (never cc, mods removed, a few free packs--I'm still trying to decide what packs to buy first).
One of the most frustrating examples is when a parent is feeding an infant in the highchair, and I tell the parent to put the infant to bed in the crib. The parent usually walks to the crib without the infant, then returns to the highchair and picks up the infant, and then returns to the crib and puts the infant to bed.
I've also seen a parent help an infant explore foods in the highchair, but the infant was still hungry so I had the parent help the infant explore foods in the highchair again. The parent sat down in a nearby dining chair before feeding the infant again.
I've also had times when I've told a parent who was holding an infant to change a diaper or clean up the infant or give the infant a bath, and the parent put the infant on the floor first, then picked it up, then took care of the infant. But I don't remember whether I've seen that since the last update.
