Understanding Baby Milestones

Milestones are general signs of development that most babies reach by certain ages. They include physical abilities, cognitive skills, and social behaviors. While every baby develops at their own pace, these milestones provide a general framework for tracking progress.

Note: Every baby is unique. Some milestones may be reached earlier or later than the average. If you have concerns about your baby's development, consult with a pediatrician.

Key Developmental Areas

Motor Skills: Crawling, walking, climbing, and fine motor skills
Cognitive Abilities: Problem-solving, memory, attention span
