here here Dulwich Mum. They are here to learn, not to be exploited. au pair ?60-?70 a week ( dep on how many hours- mine just 15 hours) plus food and lodgings- no qualifications. Nanny ?500 a week - qualifications, CRNB check, healthy meals, first aid, knows the area, can drive, networking etc. If you have ever had a competent nanny phoning you from hospital with your 18 month old having a febrile convulsion who know exactly what to do - you would understand why nannys are nannys and worth every penny you pay them in the early years.
