The game doesn't work properly when there is an infant in the household

Today I had to shift-click and cheat my Infant Sims' needs as they nearly starved while I was actively trying to feed them the whole time. The mother Sim kept canceling the action to take the infant to the high chair in favor of autonomously deciding to "put down" infant and "check on" infant. I told the mother Sim to take the infant Sim to the high chair, they walked by the high chair, added "put infant in crib" to their action list autonomously and queued up "check on" infant after. I was trying to feed the infant Sim and was unable to because the mother Sim is obsessed with picking up and putting down and checking on the infant.

Same issue here.

My game experiences simulation lags as soon as an infant is part of the household. All interactions with the infant get stuck and take several 'Sim hours' to activate... when they don't fail entirely. On top of that, all the Sims in the household constantly cancel their actions to interact with the infant, which makes the issue even more complicated.

Ok so I am very frustrated by this im literally on the verge for losing my infant because my sim just wants to stand there every time I get her to care for the baby please help
