At the age of 3-4 years, your child has started developing all his skills be it fine motor, gross motor, verbal or analytical. He understands whatever is conveyed to him not fully but partially. He is now acquiring the understanding of the simple analogies. Simple analogy means comparison between two things.
What you need to know:
You are the pillar of support for your child. Train him to develop his various skills. Discuss with him on topic centric things. Read out story books. Familiarise him with new words. Design some craft which will involve different activities. Let him distinguish one from the other; like colour a circle, give him instructions to cut it and paste it on a separate sheet. This activity involves a series of activities - first colouring, then cutting it, leading to pasting.These are complex actions for your kid to understand, so act as a facilitator. Often give him puzzles to solve.
