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.
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.
