Why would father be more suited to care for Christopher?

Christopher's father. He works in the boiler business. He is the sole caregiver of Christopher, and has been since Christopher's mother died, two years before the start of the novel. Christopher's father looks after Christopher, knows all his habits, and understands the way Christopher works. Chris's mother could not take the pressure of both marriage and dealing with Christopher. I think father just understands Chris better than anyone else. He does make mistakes but only out of looking to protect his son.
