For example, Lego's would be an excellent gift, since they can be made into multiple designs, depending on the imagination of the child, without being dependent on all parts being present in order to use them. Video's are an excellent gift. Pay attention to the shows the child watches on television, and then try to find video's of those characters. Puzzles are another item that can be a good gift, however as a word of caution, these usually have a limited lifespan, since pieces get lost. This is a true case of the sum of the parts is greater than the whole.
Many children have fixations with clothes, for example shoes.
A new pair for the holidays can be an excellent gift. Gifts which can be used indoors and provide the child with exercise are excellent. Toy computers that teach math, reading, etc. are also excellent gifts. They provide for hours of fun, especially if there is a multi-sensory component to them that allows the child to be creative. Some of these even talk to the child.
