1. All seven sensory systems (vision, hearing, touch, smell, taste, proprioception and vestibular perception) are used for learning.

For example, when you tell a story to your baby, you can say, "There is a little girl with red hair. She is wearing a very comfortable coat. First, she carefully crossed a wooden bridge and went to the forest. She wants to pick strawberries. As a result, she ate a sour and sweet red strawberry. After picking many strawberries, she lay on the grass, smelling the fragrance of the grass and listening to the birds singing. When the wind blew over her face, she felt very comfortable.

3. All the senses are used. Of course, next time the mother can take the baby to the park to actually perform the story.
