During the drive to the hospital, Stanley and Ellie cross a railroad track just before the arrival of a train. Immediately afterward, we can see the traffic behind the car, and the stream of cars is undisrupted, with no sign of the train.
The baby is not christened until he is about 6 months old, named after his maternal grandfather, to his surprise. There is no clue given as to what he would have been called in the first six months of life.
The baby is christened "Stanley Banks." It may appear to be a goof that he is not christened "Stanley Dunstan" or "Stanley Banks Dunstan." However, in Roman Catholic and Anglican/Episcopalian baptisms, only the Christian names are used, not the surname.
