- Observation skills: The child observed the movements and actions of their younger brother, such as crawling and grasping objects.
- Object permanence: The child may have noticed that even when their brother was out of sight, he still existed and could be heard or seen again.
- Cause and effect: The child may have experimented with actions that caused a reaction from their brother, such as making a noise to get his attention.
- Social skills: The child practiced sharing and taking turns with their brother, as well as communicating non-verbally through gestures and facial expressions.
To continue developing these concepts, parents can encourage their child to play with other children of different ages and abilities. They can also provide opportunities for the child to explore cause and effect relationships through simple experiments or activities, such as dropping objects into water or building structures with blocks. Additionally, parents can model and reinforce positive social behaviors, such as sharing and taking turns, in everyday interactions with their child.
