I didn't go into nannying via the traditional route. I have a degree in a subject that is related to childcare, have done the ICP and have experience. I don't have a specific nanny or childcare qualification.
What I'm wondering is what qualifications you have and do you feel they improve your work? My CV is good with what I have and I've never had trouble finding work so not looking for something that will just make my CV better/appeal to parents, but something that will actually make me better at my job, that can't be gained from experience.
What have you done? How did it help your work? What would you recommend?
