Cognitive delay in infants

Cognitive delay in infants: How a child perceives the world

Cognitive development is the process by which a child learns to think, understand, remember, solve problems, and explore the world. In the first year of life this development occurs at an incredible speed: an infant's brain grows and creates millions of new neural connections every minute. Delays in this area can be hard to notice, but there are certain milestones.

Stages of cognitive development up to one year

• 1-3 months: The child learns to focus gaze, track moving objects. They begin to recognize faces and the voices of close ones. For more details see the article "Development of newborn vision".
• 4-7 months: This is a time of active exploration. The child puts everything in the mouth, examining objects. They start to understand cause-and-effect relationships (if you shake a rattle, it makes a sound). The concept of object permanence begins to form — the understanding that an object exists even when hidden.
• 8-12 months: The child actively searches for hidden objects, imitates simple actions and gestures, understands the function of some items (e.g., putting a phone to the ear). They begin to solve simple problems, such as how to retrieve a dropped toy.

How to stimulate cognitive development?

The best approach is to create a rich and safe environment for exploration. Your role is not to "teach" but to provide opportunities.

• Offer a variety of toys: Different shapes, textures, colors. For guidance on choosing them, read the article "How to choose safe toys".
• Play simple games: "Peek-a-boo", object hide-and-seek, games with sorters and stacking rings. We have a separate material on developmental games.
• Communicate: Name objects, comment on actions. This is the foundation for developing thinking.
