What are the motifs in Paris to the Moon by Adam Gopnik?

Family Life often took center stage in this story. Adam and Martha brought their infant child with them to Paris, which is essentially where real family life began for them. The demands of this family life were readily embraced by both parents, even as they coped with the wholesale replacement of their New York routines with the new demands of living in Paris. The cocoon of the natal family became even more powerful than usual for the Gopniks, surrounded as they were by the foreignness of France.
