Sims 2 did it best with Sims 3 in second. Sims 4 did it worst because of the teleporting and the fact that they can't bother making proper fridge, dishwasher and microwave opening animations. It also feels like they're reusing the adult animations for everything while Sims 2 and 3 had unique animations for kids.
Thanks for your input, I do feel that the sims 2 and 3 had more realistic kid animation like you said. I wish the kids in Sims 1,2, and 3 could use the microwaves in like in sims 4. Thank you for watching, I really appreciate it!
