I bought this item as a gift for my grandson's second birthday. Both he and his 4-year-old brother are enjoying it very much. 1. The LEGO Duplo pieces are of a size that is easily manipulated by small 2-year-old hands; 2. The Mickey Mouse characters and train theme are universally popular with this age group; 3. The birthday theme of this set (cupcake with a candle,on top, presents, etc.) made it an extra special birthday gift. A big hit all around!
