I tried to log in and make a suggestion in the Discord channel about infants gameplay, but I was not able to write anything there, it simply wouldn't let me.
I would be so thankful if someone, who is able to write in Discord, could copy/paste my suggestion there.
My suggestion: If a player has autonomy off, then the Sims shouldn't check their newborn/infant on their own.
I always play with autonomy off, but my Sims STILL check their newborns and infants by themselves and cancel their actions. This behavior would be ok if I have autonomy on, but I expect to have no autonomy when autonomy is off.
For example, I play with autonomy off. The dad is doing something like tending the garden, while the baby starts crying. I tell the mom to look after the baby, because she is already in the next room. But still the dad autonomously stopps tending the garden to run inside the house and also look after the baby.
This is beyond annoying! I as a player am able to take good care of my Simsbabys. If I choose to play with autonomy off, then I don't want the game to do this for me.
