When getting rid of head lice everyone in the household must be checked. One person that can be considered part of your family is your nanny. Many families have nannies that spend at least 8 hours in their homes with their children, therefore your nanny can get head lice as well. A family was checked at Hair Fairies where one of the children was known to have head lice. The mom said that she must have it because the child slept with them every night. She told the nanny I don't believe you have it but you should get checked as well. The end result was the nanny had more than both mom and dad combined because she spent many hours of the day with the child: feeding her, reading to her, bathing her, putting her to bed, etc. Nannies spend almost as many hours as the parents do with the children and sometimes more. Always make sure to get your nannies checked as well.
