Many parents have special dietary restrictions for their children, whether it’s a sugar-free diet for general health purposes, or a lactose free diet for allergy purposes. Keep a list of all rules about food on the refrigerator, and go over them with your nanny and child, if your child is old enough to understand. This helps the child self-regulate, and also doesn’t make the nanny the bad-guy in what could become food wars.
If you want your child to eat a certain number of fresh vegetables and fruits, either make sure that you have the foods ready for the nanny to prepare, or make sure that you allow enough time for the nanny to purchase these items, with your child in tow, on work time. Another option is sending the nanny to the store on her regular hours while you watch the child for that time. If you want the nanny to cook for the child, you should cover this in
the nanny's interview.
