My daughter is a HUGE American Girl fan. She has several dolls and many of the books. She has even seen the few movies they have made. While I feel that much of what AG does is designed to sell overpriced dolls I do not fault them for that. The site, books, and stories have helped build my daughter's self-esteem . The books also provide valuable history lessons, and I have really enjoyed reading them with her.
The site is more of the same, with fun games and activities. I feel safe letting her wander around the site on her own as the content is very appropriate for her at 8 years of age.
