I bought this for my great nephew - 18 months old who is already learning to count and learn his colors. I also got him a dino puzzle by Melissa & Doug. Both items are really great. They are very durable and colorful so he likes playing with them and putting the shapes back in their places. The number puzzle is fun because when you take the number out, there are pictures under each number for example - take out the three - there are three turtles (I may have the wrong animal but you get the gist!!). His 3 year old cousin that visits often also loves playing with them so they have a good age range.

I was enchanted with this fascinating book on barn conversions. Barns are great relics from our past, conveying a sense of history, but many have been ruined by weather, time, and neglect. I didn't realize how many creative architects and owners have made barns useful for both residential and commercial use through renovation and restoration. The intrinsic character of these old barns brings an integrity and charm rarely seen in new construction. In many gorgeous illustrations, Rooney describes the history of barns, their adornment (who knew that it was all because of a 9th century pope that there are so many roosters on weathervanes?), and their use as gorgeous residences and fascinating commercial and establishments - including an architectural office, inns, and even a funeral chapel. One entrepreneur even used several to develop an office complex. If you love barns and if you like to see the past preserved in the present, you will love this book.
