We have 3 kids (including my step son) and I recently went back to work full time. DH arranged for me to have a cleaning service come to my house every other week, so twice a month). It has been WONDERFUL and it is great that I don't have to spend all weekend vacuuming, etc. However, I am wondering if its better to have them come once a month or continue with twice a month. What do you do and why?
