Do you tend to let the helper run the house - shopping, cooking, washing and ironing? How much supervision you you exert? If they are competent, do you just leave them to it, as you would in an office environment? Or do you still see yourself as primarily responsible for running the home with the helper as an additional pair of hands?
Or do you do some things? For example, do you do specific tasks (eg cooking) or is it a bit more a question of all mucking in - so you tidy a bit, the helper does the cleaning - or is that too much crossing-over and difficult for the helper to get on with things?
And most importantly - childcare. I don't work, but would need a hand with the children. How do you balance being the main carer with allowing enough contact that the children and helper are happy together?
