I think most Singapore's parents agreed with this.
Early childhood generally encompasses the first eight years in the
life of an individual. The education given during these years of a
child's life plays a very important role and helps in proper
development of children.
Early childhood education can be fundamentally termed as "Learning
through play". Recent research have shown that early eight years in
any children life are crucial time because during this phase their
brain develops and much of its 'wiring' is laid
down.
That's why at the age of 2, most parents will send their kids to
play group. Will you, as a parent, skip the paly group but send
your kids to nursery at the age of 3 instead?
