we've only had one helper and she has just signed her 3rd contract with us.
we provide sheets, she provides her own towel. we've offered ours, she prefers her own.
we do not provide toiletries. we do provide hand soap in the bathroom for anyone to use, but she supplies her own toothpaste, deoderant, shampoo etc. it has become a joke in our house that for xmas every year, i buy her "luxury" toiletries, that usually include a mask, exfoliator, bubble bath, shower gel etc. we do stock the bathroom with toilet paper, as it is a room that we all use.
we never provided a food allowance. i thought it would be a terrible waste of time for her to have to cook 2-3 separate meals every mealtime. she eats whatever we eat and she's very happy with it. she gets better quality food because of it. on new year's eve, we have a huge seafood dinner and she always joins in. on occasion, we've gone to the filipino shops and bought her some of her "own" snacks. snacks is one thing we don't generally share. we keep them up in our room (on the 2nd floor) instead of in the kitchen. mostly, it's because we can't be bothered to run up and down so often. she usually buys her own snacks.
i know that if we gave a food allowance, she would try to eat as frugally as possible to make the money last. i would feel terrible if she had just rice & old veg with a bite or two of meat, while we ate bbq steaks, salad etc.
like i said, it works for us. she's very happy with the situation, and so are we.
