Ideas
I think I'm having the same issue, on PS5... I've been playing a household with twin toddlers and two parents, and almost every time one parent would put one of the toddlers in the high chair to give them food, the other parent would come over and take the kid out before they have a chance to eat. It's been so infuriating that I've resorted to locking the other parent in a different room while the toddler is eating. It's strange because it's always the OTHER parent that takes the kid out - there's no issue when only one parent is around - and you can't cancel the interaction once it's queued up. They even interrupt what they're doing on the other side of the apartment (playing in Evergreen Harbor). Resetting the parent causes the toddler to t-pose outside the high chair as well.
