Items that have been banned from your played sims households?

Ha! Good question.
Sims are obsess with some specific objects and that board that came with Parenthood is a great example.
For me, the object that is absolutely banned is the highchair.
Highchairs don't work as intended and make my sims waste precious time, they are forbidden in my game. Instead I always add an armchair or a sofa to the kitchens and dining rooms for toddlers to eat and socialise from there.
