Want to buy a gift for nephews or nieces and you do not have kids of your own that age (or any age) to use as reference? Amazon.com to the rescue. Select the age and sex and then read the reviews of the products. By selecting things that parents have taken the time to write rave reviews about, I have become known as a legendary gift-giving uncle with great insight into what kids of any sex and age would really enjoy. And in actuality, I have no idea whatsoever.
