1. Nature of work: Babysitter's work usually needs to be carried out in the employer's home, including taking care of children, the elderly, doing housework and preparing meals. In this case, it can be regarded as part of the job for the employer to provide meals for the nanny, because the nanny needs to prepare food for herself and her family.

2. Convenience: Employers provide meals for nannies, which can save time and energy for nannies to eat out or cook by themselves, and make nannies more focused on taking care of their families and completing other housework tasks.
