सारांश	The Bayley Scales of Infant and Toddler Development (BSID), third edition, is a comprehensive standardized assessment tool developed by Nancy Bayley in 2006. It measures cognitive, motor, language, and social-emotional development in children from birth to 42 months. The scale identifies developmental delays and disabilities in infancy and early toddlerhood.	The Ages and Stages Questionnaire (ASQ-3), third edition, developed by Jane Squires and Diane Bricker in 2009, is a parent-completed developmental screening tool designed to identify children aged 1 month to 5.5 years at risk for developmental delay. It is brief, economical, and well-suited for population screening in primary care, early intervention programs, and community settings.
