Have just registered to provide over night care in addition to normal daytime childminding. been planning to do it for a while, but have rushed sorting out new bedroom ready for one particular parent and upcoming one off event. Have sorted one off rate for parent in question but wondered how much it is common to charge overnight, or what lower rate for sleeping hours. usually charge double time for care after 7pm but not sure the market or our reputation as quality CMs could cope with 12 hours at double time. Want to make it worth my while, and the associated extra costs and risks but do not want to seem like a money grabbing rip off merchant either. any suggestions ? What would a qualified all night babysitter expect, or a sleep in nanny? Any ideas welcome
