I don't think that playtime should always be educational. While I know some people do, I think kids should be able to just run around and be crazy sometimes. With that being said, I do believe that education is an important aspect of play. We've found some great products from GALT Toys that really bring out the fun, but sneak a little learning in there too.
As you know, Charlie is really working on his alphabet skills at preschool (and home) and loves anything he can do with them!
