Longfellow continues to describe the children as creatures of pure joy, "Singing with the early birds," representing their happiness and carefree nature. He observes their curiosity, "Seeking where the brooklet glides," and their imagination, "Building castles in the air," highlighting the boundless possibilities of their minds.
The poet contrasts the innocence of children with the complexities of the adult world, noting that adults "trouble the stream/From their dreams of childhood flee." He laments the loss of childhood's simplicity, acknowledging that as we grow older, we may lose touch with our inner child and become burdened by life's responsibilities and worries.
Longfellow ends the poem with a message of hope and encouragement, urging adults to reconnect with their childlike spirit. He implores us to "Go seek again your light bird" and "Call her by some tender name," reminding us that embracing our inner child can bring us joy and rejuvenation in the midst of life's challenges.
Overall, "Children" is a nostalgic and poignant tribute to the beauty and fleeting nature of childhood. Longfellow captures the essence of a child's world, encouraging us to cherish and embrace the child within us, finding joy and inspiration in its simplicity and wonder.
