A parent I know has asked a few times if I can pick up their child from school (child in same class as my ds) and look after them for a few hours.
Whilst I don't mind the occasional ad hoc I am concerned that they might start regularly asking me and I don't want them to rely on me as childcare.
They've offered to pay me but I'm not interested in taking money for it and don't want to be a childminder.
Any suggestions how I can politely get this across if I'm continued to be asked?
