Every kid has their own obsessions. Dolls, plushies, dinosaurs, remote controls, cell phones — they might have a toy box with a wide range of playthings to keep them entertained, but there’s a firm favorite they always reach for first.
Researchers call this phenomenon “extremely intense interests” (EIIs), and have found that they start to emerge at around 18 months of age and are evident in around a third of preschool-aged children. For lots of children, maybe even your own, this obsession revolves around cars. And although the sex divide in the toy world remains, it’s not only little boys who are drawn to all things with wheels.
