This resource provides information to assist parents, family members, early childhood teachers, caregivers, and other adults in promoting the learning and development of young children ages birth to three. It is a companion to the Nebraska Early Learning Guidelines for Ages 3 to 5, and uses the same format and domains of development. This voluntary guide has been developed to provide information about: (1) what to expect in the development and learning of young children from the time they are born to age 3, and (2) what adults can do to provide experiences and environments that support learning across developmental domains. These guidelines address seven domains of development and learning: (1) social and emotional development, (2) approaches to learning, (3) health and physical development, (4) language and literacy, (5) mathematics, (6) science, and (7) creative arts. Each domain contains information specific to the development of skills and knowledge in that area, including information on widely held expectations, learning in action, and the environment. This document is designed to address the growth and development of children from birth to age 3. It is further divided into two distinct age categories: birth to 18 months (Infants), and 18 months to 3 years (Toddlers). This was done intentionally so that the age breakdowns would match Nebraska's child care licensing statutes as they relate to adult:child ratios.
