By this age, children want to independently do all their activities. They want to learn everything through exploration. We, as caregivers, should help set a prepared environment for them wherein they learn by exploring the world around them, whether it's through nature walks, going to sports centres, or visits to the zoo.
A few activities that can benefit them are working towards language development alongwith social skills. They are also continuously working to refine their gross and motor skills. At this age, children love to indulge in imaginative play and enjoy pretending.
