Understanding Baby Development

Baby development refers to the gradual growth of a child’s body, brain, emotions, and communication skills. While milestones provide general guidelines, every baby develops at their own pace.

Key Areas of Development

• Physical development – movement, strength, coordination

• Cognitive development – thinking, learning, curiosity

• Language development – sounds, words, understanding

• Social development – bonding, interaction

• Emotional development – expressing and regulating feelings

Healthy development depends on nutrition, sleep, environment, and responsive caregiving.
