Open Question: how can I get a job in retail when all my work experience leads toward working with children?

I am 16 looking for a summer job. I am working on my resume and they say that you should write things in your resume that leads toward the position you're applying for. I don't really mind working with children again but I wanted to try something new. The problem is that all the work experience I have (last 2 jobs) leads towards working with children. I signed up for summer youth but I don't want to just rely on tat. Any job suggestions or tips on how I can tweak my resume? Please Help!!
