I have an assistant and I do run errands and leave the home about half the time that she is here. Thats the whole point of having an assistant, so that I can actually get a break without that being a problem for the DC parents. Not every thing is available in the evenings. But if I was the OP, I would certainly check on the ratio regulations. I would also be concerned about how much English the assistants actually know. Are they able to do their job completely? Instruct the kids? Handle phone calls? etc?
