Good luck. We hired on the same basis but it just hasn't worked out. In future we will only be hiring someone who already has experience working with a western family. We just don't have the time to micro-manage someone until they 'get us' and i kind of think it defeats the purpose if you have to tell them what to do every step of the way. Our helper hasn't made life easier for us but actually harder because i now have to manage her and our two kids. I'm sure that some helpers learn fine how to look after a western family but ours just doesn't seem able to. Our family is very relaxed but for her everything is a task she just wants to get finished. Our 17 month old constantly gags on his food because she stands over him shovelling food into his mouth when he hasn't finished the first mouth and despite us telling her to sit down and make sure he eats slowly. When she bathes him it's all done within 5 minutes despite the fact that he loves the bath and when we do it we let him stay in there until he wants to get out. She lets him cry and cry in his bed despite the fact that I have told her not to. He is a good boy and cries when he's done sleeping or when something is wrong- like his foot is caught in the cot not just for the hell of it. The other day i came home to hear him crying hysterically in bed and it was clear he had been doing it awhile his face was so red and he was in a sweat. His whole leg was trapped in his cot bars and she was in her room doing nothing.
She can't talk to him properly, never uses please or thank you so everything is an order. She ruins our dinner nearly every night to the point that eithe i cook or we order in most nights. She doesn't understand that we cook with only a little oil despite us telling her time and time again. Last night she made bangers and mash- not hard at all but the mashed potato was swimming in a pool of golden oil and she must have used an entire clove of garlic! It was disgusting. Another meal into the bin without even a bite taken. Not forgetting that my husband has had severe food poisoining three times since she's been here each time having eaten food she cooked that i wouldn't touch.
Anyway, sorry about the rant but it's probably best to scare you a little so you make an effort to get things right from the beginning. I think if you let things go at all at the beginning it is too hard to get things back on track later. If our helper was better with the kids- she appeared to be at first but actually is no good, i would have sent her on cooking classes etc. As is she's not worth any further investment. She is paid $4000/month, we bought her air-con for her room, new bed, towels, clothes, toiletries, everything in fact and we have nothing to show for it but more stress. She simply won't make the effort to do what we ask her to do. I think a lot of helpers think westerners are easier employers, softer etc and probably we are simply because most of us come from countries where it is harder to afford full time help so we have no experience in dealing with them.
Get as much info as you can about working with them and it might all work out fine. If it does life can be a hell of a lot easier and more enjoyable. Good luck.
