## Child Development Stages ### 12 - 18 Months 1. **Walking**: The child begins to walk independently. 2. **Ball Play**: The child practices rolling a ball. 3. **Building**: Engaging in stacking objects or building simple structures. 4. **First Words**: Beginning to speak simple words or phrases. 5. **Interacting with Pets**: Engages gently with a pet, such as a dog, indicating some level of understanding and care for animals. ### 18 - 24 Months 1. **Running**: The child starts to run more confidently. 2. **Kicking a Ball**: Developing basic motor skills through kicking a ball. 3. **Jumping**: Begins to jump, showcasing balance and coordination. 4. **Pretend Play**: Engages in pretend play, such as holding a toy microphone and pretending to sing. ### 2 - 3 Years 1. **Tricycle Riding**: Starts to ride a tricycle, enhancing coordination and balance. 2. **Throwing a Ball**: Gains skills in throwing a ball with more precision. 3. **Building Towers**: Constructs taller block towers, indicating problem-solving skills. 4. **Identifying Shapes and Colors**: Begins to identify and name shapes and colors, supporting cognitive development. 5. **Naming and Expressing**: Uses phrases like "I am [Name]" to express identity and build social skills. ### Graphical Representation - **Icons**: Black and white stick figures depict children engaging in various activities. - **Progression**: The layout shows a chronological progression from 12 months to 3 years, illustrating key developmental milestones in motor and cognitive skills.
