Are you a big baseball fan? Is your husband? Do you watch a lot of games on television? Are you planning to take your kid to a professional game? Or is your little one going to start t-ball next spring? You can use My Baseball Book by Gail Gibbons to explain the (often confusing) game to your youngest fan. It was recommended to me by a librarian and I think it's a keeper. I only wish we would have had it before Norah started t-ball earlier this year.
