misaryeo,
Some curse and swear on helper, some are grateful that a helper is around.
There are alwasy pro and cons.
Pro: Someone to take care of kids, housework, extra pair of hands around.
Cons: Some can be cunning and attitude (Depends on your luck at times), their understanding of what you really want, less privacy, need to think of place to let the helper sleep, extra mouth to feed, less income as you have to pay the helper.
But my stand is, it really depends on what you want, and I always find managing helper is like a HR job. Once you manage them correctly and set your priorites right, they will be a great help around. No regrets so far on our part.
