Reading is Fun (RIF) is a wonderful literacy website for adults and kids. It is actually the oldest and largest nonprofit literacy organization in the United States. There are book lists, games, articles, brochures, and more! If you use the link from this paragraph, it will take you to the main site where you can find resources. These are GREAT for parents!
If you follow the Reading Planet link, you will go to the child version of RIF for 6+ years old. There is a 0-5 year old section, too. You can find this by following the top link, click on "Kids" in the top right. It gives more options.
