How do I stop my sims from picking up their toddlers for no reason?

It only happens when they're doing nothing. My playstyle is weird because often want my sims to do nothing. Like yesterday when I tried playing both parents are supposed to be sitting on the sofa, and I want them to stay there because in my mind they are relaxing. The dad kept getting up to pickup a toddler though so I got frustrated.

I just added Nraas animator and so far it’s helping. I gave both parents a sitting idle animation and they haven’t gotten up yet
