These days, toy trends come and go by the month. When a toy is mass-produced and generic, it’s easy to see why kids move on to the next so quickly. So how are grandparents supposed to keep up with what’s “in”? MarbleSpark says it has a solution in the personalized book, “Following Featherbottom,” which can grow with a grandchild for years. It uses unique details like the child’s name and birthday to insert the child into the plot, allowing their imagination to expand with the story. It becomes a keepsake. $32.95 from marblepark.com.
