Final answer:
Two main themes in the poem are resilience in the face of loss and the continuity of life, exemplified by the repurposing of the father's clothing for the children and the carrying on of daily routines.
Step-by-step explanation:
The poem depicts two main themes: resilience in the face of loss and the continuity of life. These themes are developed through the narrative of repurposing the father's clothing for the children, signifying life moving forward despite the pain of death, as shown by the lines 'Your father is dead. From his old coats I'll make you little jackets;' The idea of resilience is further supported by the directive nature of the lines, 'Life must go on; I forget just why.' The presence of everyday tasks amidst grieving, as described in 'Anne, eat your breakfast; Dan, take your medicine;'suggests that life's rhythms persist in spite of personal tragedy, reinforcing the theme of continuity.
