I think it depends on where you are....? I have done this. I had been quite sick and needed help when I was first coming back. It cost a lot and long-term my wouldn't have been worth it, but if it's a short-term, or temporary thing, it could work. My first week back I had her for 3 hours/day, but obviously chose the 3 toughest hours...I think it was 8:30 - 11:30. I used my replacement who charges $10/hour. Where I am I have a list of replacements/assistants and they all charge between 10-15/hour.
