I was surprised not to see this on the compilation list or find an open report. In my game, the rapid escalation of hunger for an infant in a highchair being fed finger foods leads to freezing and lag in the game. All I could find was a two-year-old thread in the gameplay section: Infants Hunger Goes Down Too Fast W/Highchair | EA Forums - 8728034.
In my save I can replicate this 100% of the time. Put an infant in the highchair when the hunger bar is yellow and start the feed finger foods by a parent. The parent gives a couple of swipes, the infant's hunger bar quickly deteriorates to red, leading both parents to develop "feed" in their queue. At that point everyone just sort of freezes, doing nothing, or taking a long time to figure out how to handle.
My workaround now to prevent freezing or lag is to pause the game, drag the plate to a trash can, cancel out anything in the parent queues. I then queue bottle or breastfeed for one of the parents and send the other to work on a skill. I then unpause the game and it clears up quickly.
I do believe this is a bug since I doubt feeding finger foods should lead to a starving infant and freezing/lag. My computer far exceeds specs required for the game so freezing/lag occur very rarely for me.
