I also often cancel out hand washing if it takes too long.
Once my sim had a baby that wouldn't stop crying even for a second no matter what I tried. It was well fed and clean and had a quiet room but probably glitched. I couldn't age it up as it was one of my 100 babies children. So I put the baby outside right down the back of the sims lot until it was time to age up (feeding it at regular intervals).
I felt very evil but the other sims in the house were able to sleep and function and I couldn't hear that awful crying. It seemed the only solution. It grew up to be the one child who just couldnt seem to get an A as a teen, 3 younger siblings aged up first.
