Kidshealth.org
What I like about KidsHealth is that it is split from the very start into three very distinct sections - For Parents, For Kids, for Teens, addressing each audience in a style and language that is wholly appropriate.
Laid out in a magazine-style, each section is packed full of articles and features.
Heat sickness and bullying are dealt with in the parenting section, and bike safety and weight issues are addressed for teens.
As well as all the advice, there are recipes and activities your kids and teens can try for themselves, which is ideal for keeping them occupied during the school holidays.
And The Games Closet in the Kids' section has some great educational games and movies geared towards teaching them more about their own health needs.
