Can anyone explain what is meant by 'continuous sole care' in regards to au pairs looking after under 2s? We'd need someone to take our 18 month old to nursery in the morning (DH leaves for work at 7am and nursery opens at 7.30) and very occasionally do pick up if DH running Kate but would literally be a few minutes. Is that something that would be up for negotiation or is it a definite no?
