这个没什么问题。无论是请保姆还是请月嫂。都要事先签好合同。如果是按周或是按天算工钱的。比如300/天。合同要写好$15/hour or whatever minimum wage in your state. Meal time and sleep time and any break time more than 30 min are unpaid. Employer provided meals will be valued at $20 per meal and count towards compensation. Or 300/day cash pay whichever is greater.

然后每周写明工作时间，让保姆签名领钱。我觉得就算是月嫂，每天给她5小时uninterrupted rest time 也是应该的。
