Infancy (0-2 years)

During infancy, babies grow and develop at an astonishing rate. It’s a time of immense learning and exploration for them. Here are some key points to keep in mind:

  • Physical Development: Infants rapidly gain weight and grow in length during this stage. Their motor skills also progress, from reflexive movements to purposeful actions like reaching and grasping.
  • Cognitive Development: Babies start to recognize familiar faces, objects, and sounds. They become more curious and begin to understand cause and effect.
  • Emotional Development: Infants form attachments with their primary caregivers, laying the foundation for emotional security. They express their needs through crying, smiling, and other gestures.
  • Social Development: While mostly focused on caregivers, babies start to show interest in interacting with others and may engage in simple forms of imitation.
  • Language Development: Although still non-verbal, infants babble and make sounds to communicate. They also start to comprehend simple words and gestures.

Understanding these milestones in infancy can help caregivers support their child’s development effectively. Each child is unique and may reach these milestones at their own pace, so it’s essential to provide a nurturing environment for them to thrive.
