Final answer:
The crying baby is considered 'being a Charles' by the family because they attribute certain actions and behaviors to Charles's character.
Step-by-step explanation:
In the story, the crying baby is considered to be 'being a Charles' by the family. This means that the family attributes certain actions and behaviors to Charles's character. The family may have observed certain traits and behaviors in Charles and now attribute those same characteristics to the crying baby. For example, if Charles was known for being fussy or demanding, the family may attribute those traits to the crying baby when they refer to them as 'being a Charles.'
