I had good childcare with the butler - but I honestly have not tried the nanny at all - as the only household but one that had children had a butler, so I had no need. The one with neither had a stay at home mom and a dad that only had to work 3 days a week. I generally wait for sims to have kids until they are high in their careers and skills - so by then they are home more than working - and I also limit kids to 2 - with the second one not born until the 1st one is pretty near teen age. LOL. So no issue. Luckily my few multiples had butlers and at least one stay at home parent.
