By ages 3 to 5 years, children already have their own interests and favourites, usually revolving around classic themes such as wildlife, space exploration, and superheroes. However, there are instances where their impulses can sometimes result in momentary interest. The best toys for children at this age hold their interest while promoting cognitive and physical development. This is also a great age to encourage intellectual social play. Solving puzzles, building structures with blocks, and pretend play are all great options for children at this stage.
