When you are shopping for a magic kit for your kid, make sure that the magic set you finally select is specifially for them. Many magic kits on the market are “for ages 7-107″…or something like that.
When a magic kit has a wide age range, it means that some of the tricks will be right for your kid and some won’t be appropriate for thier age range.
Something to keep in mind when your kids is starting a new hobby (like magic tricks) is that you don’t want to get them frustrated with tricks that are above thier level. You want to keep as much stuff in thier range until they have a definate liking to the new hobby and are willing to put in more time.
Hope that helps you with selecting a magic kit for your kid!
