Body Hygiene
I found this resource to be the best because it supplies parents with numerous amounts of information while being organized and easy to navigate. Parents can check this particular page for information regarding body hygiene, or use the side bar to easily find information regarding other hygiene related topics. I think that this website would be best used to provide parents with accurate information and help parents see why hygiene is important and how to best implement it at home. This website is also trustworthy as it is created and curated by the CDC. Finally, this website is clear and easy to use so many people with varying technological knowledge will have a fine time navigating it.
I would probably include it in a newsletter home at the beginning of the year. It might explain that there are lots of kids in small proximity to each other (for all first time parents with children who are new to school) so hygiene is important so that everyone will stay healthy and stay in school. Then have a link to the website for more information and tips.
