Know their parent’s morals so you can know which gifts are appropriate. Are their parents strict on movie and television ratings or subversive material? Then maybe you should avoid getting the Ren and Stimpy box set and go for some classic Mickey Mouse cartoons. Try getting gifts that inspire hobbies, like a book of magic tricks, a crystal growing kit, or a do-it-yourself volcano. Even better, make gifts with your niece or nephew. You can easily create interesting shapes out of clay, or make homemade slime, or craft a collage art project they can hang on their wall as a constant reminder of the fun they had with their aunt or uncle.
