Childhood Language Acquisition as a Caffeine Alternative?

Nope.

But childhood is a critical period for language acquisition because it presents the developing mind of the child with full language immersion.

Like an American living in a foreign country, learning the language in order to communicate is, for a child, a sink-or-swim endeavor. Children are born into a world where adults speak to them and to each other; where they have needs and desires, but no means by which to express themselves. Therefore, children learn and acquire their language skills at every waking moment, fully open and receptive to all feedback from the adults in their lives, with no preconceived notions about languages to interfere with their learning.

For this reason, it is essential for children to be encouraged to read, and to express themselves properly and extensively through language. Reading is essential for the developing mind of a child to grow into the proper format and usage of their language.

Through active and frequent reading, both with their parents and on their own, a child will acquire the solid grammatical and linguistic foundation that will accompany them for the rest of their lives. Imagine that.
