Step-by-step explanation:
The child from stanza 4 of the poem is receiving nurturing love from his mother. This is supported by the line "Her embrace a warm cocoon." This line conveys a sense of comfort, safety, and love, much like how a cocoon envelops and protects a developing butterfly, symbolizing the mother's nurturing nature towards her child. The warmth and protectiveness of the embrace are indicative of the nurturing love that the child is receiving.
