I think it’s impersonal nature of the gifts that make them valueless. Who knows? Maybe the daughter will turn into a heavily tattooed heavy duty mechanic, and the son will be an interior designer with no interest in sports. I’d rather a Christmas ornament every year that reflects what the child’s interests are. Something that shows you are paying attention to the child. They could each have their box of ornaments that they are in charge of putting up every year. Make it a memory.
