Ideas
This appears to be much worse than the last time I played infants early last year. Check Infant is popping up for both parents and for the parent with queued infant care actions, it's wiping those out. I've added feeding and changing actions but if the infant is crying the parents start acting autonomously. My Sim has been told to change her, clean her up and then feed her in the high chair (she's just started exploring foods) but Check Infant appears and one parent gives her a bottle while she's screaming because she had a diaper blowout. So she keeps screaming because she still hasn't been changed. The other parent has Check Infant too but is waving their arms that they're being obstructed. If she's crying because she's tired, I'll queue up actions to put her in her crib and tell her a bedtime story and put on a lullaby, but Check Infant appears and the parent puts her to bed in the downstairs travel crib and ignores my instructions, or they'll ignore the fact she was supposed to have her diaper changed and put her down. I tried making her a Calm infant but she's still a real screaming, sobbing crier. I'll be ageing her up today, it's too frustrating.
