KidsHealth is a website of the Nemours Foundation, which "is dedicated to improving the health and spirit of children," and is the most visited children's health site on the Internet. The site is easy to navigate and every article is reviewed by a medical expert in the field.
The site has lots of cool features. The Kids' Talk section answers questions like "Why do I yawn?" and "What happens to swallowed gum?" The site also has information about People, Places and Things that Help Me, such as physical therapists and dialysis, has sections on the health problems of both children and adults, and the Watch Out section tells children how to play safe in a variety of scenarios.
One of the best features is the Recipes section, which provides recipes for children with diabetes, celiac disease, cystic fibrosis, and lactose intolerance.
KidsHealth is a wonderful and really interesting site, and I encourage you to check it out!
