CV: My childcare experience

Here is an example of an answer one of our nannies wrote:

My cousin has recently had a baby, and I've been very involved in helping to look after her. She's actually 6 years old now so not so much of a baby, even though I still see her that way! I also have experience in mentoring roles in school. I often lead sectional groups in the school orchestra, in which I helped the younger students to practice their music, encouraged confidence, and gave them somebody to look up to.
