I was so unlucky as to get triplets with a single mom living alone with a dog as my first experience with infants, and let me tell you, it's been a nightmare.
The random decisions to 'pick up' and/or 'put down' is the cause of about 70% of my frustrations. Don't know how many times I've yelled: JUST LEAVE THE KID BE!!!! or DON'T PUT THEM DOWN ON THE FLOOR, I SAID INTO THE CRIB!!! Sometimes these actions gets prioritized before other things I've told them to do with the same kid or antoher kid with worse needs. And it's extra annoying because you can't always do anything about it and if you do try to cancel or reset the sim it will most likely disturb the plans you had anyways or end up with kid being left on the floor. This can make something so basic as putting and infant into bed take soooo much longer 😞
The 'check infant/toddler' interaction I would say cause about 30% of the frustrations I have. This is less disruptive if you just stay on top of it and pause regularly to cancel these. It's still annoying, but at least I understand the importance of this happening autonomously. But it should have some sort of condition. Like if there is some sort of actions in the queue that involves care for an infant/toddler, the 'check'-action should not appear, cause it probably means the player is on top of it.
I also find having another caretaker around, like a nanny will complicate matters. If you tell your own playable sim to go feed an infant they will stand around and wait because apparently the nanny is on their way to interact with the infant. Interactions with NPC should just get cancelled if the player has queued an action with a playable sim
From what I myself experience and observe from gamers on Youtube, queue management in Sims 4 is pretty bad in itself with actions or sometimes the entire queue just randomly getting cancelled and sims sometimes taking ages to decide to finally do what you told them. By now I don't think there's any hope of this getting fixed though :'( It seems to be something with they way they've made it and also multitasking is probably not making it easier.
