I must have lucked out! My butler rarely sleeps but otherwise he's very efficient.
There's always one fresh meal on the table, he cleans as soon as there's a puddle or spoiled food or any dirty surroundings, he feeds the toddler, he plays with the toddler, he does the gardening, he repairs anything as soon as it breaks.
My sims have had to do literally nothing around the house. One time I had a visitor who went around breaking everything and the butler followed him fixing the aftermath - it was funny!
