A quick search on the bar said this was unique.
every time I queue up my parent sim to take care of her infant, she puts the baby down to sit down between each step, even going from the changing table by the crib to the crib has to be held up for the sim to go for a sit down. Tasks already take so long, but it took her all day to feed, change a diaper, and give a bath, interrupted as well by other sims. That cry is frustrating enough without the parent sims taking extra time like it!

The same issue is present for Sims. It has it's own thread here: Routing/Sit down issue on several interactions | EA Forums - 12348200
