“ shows a lot of preparation and that this person takes their jobs seriously,” says Rachel Charlupski, founder of the Babysitting Company, who calls them “kid kits” and says every babysitter is encouraged to get one when they start working with her company. Plus, you’ll likely impress your employer. Your bag might not exactly be bottomless, but if you stock it full of the right essentials, your babysitting kit will help you be the best babysitter you can be. This isn’t a pie-in-the-sky-dream you can make this level of preparedness a reality. You arrive at every job with a magical babysitting bag filled with everything you need to keep things running smoothly. Imagine yourself as an ultra-prepared Mary Poppins-type sitter.
