Why does early childhood development important for child's later development?

It is their foundation of learning and discipline.

Early childhood development is important for the future development of a child because it has an impact on their life physically, mentally and emotionally. Their early years of learning will allow them to successfully develop social and cognitive skills at a quicker pace.

early childhood development is very necessary for every child.. from age 0-6years a child has special powers i.e. human tendencies, absorbent mind and sensitive periods  which help him to learn.. he doesnot only learn but also incarnates the impressions from his surroundings .. for a child , the early years of his life are very important , it is considered as the foundation or strong pillars of his personality.. 

because the brain development depend in early child development which lead to learning of most the skills the he will use later

The first five years of a child's life are fundamentally important.They are the foundation that shapes children's future.

several childhood education researchers have come to the conclusion that what a child learn at an early age go a long way to determine what such child will end up to become. As a teacher in Elementary school, i have come to understand that in the formative years of children they are easy to mold and it is also easy to inculcate good mannerism into them all these which will grow with them and make them a better adult in their later year.

early childhood development is very important for later child's development. it is a base for a successful and confident adult later. from my personal experience i have understood the utmost importance of early childhood development. i have one of my friend whose early childhood development was nil and she faced a lot of problems later in her life. because of the lack of early childhood development she could not become a confident person in her later years. 

As a professional teacher in Elementary pupils, early childhood development is very important for child's later development because this development is the foundation of the child's learning. Whatever he/she learns during this period would still continue until he/she reaches adulthood.
