What are the substitutes for eager children?

"I am eager to have a son", is it looking forward to having a son, or looking forward to the son who has not left home? Or do you expect your son to succeed?

1, I hope my son will succeed: I hope my son will become a dragon.

2. I hope my son will go home: watch the door, lean on the door, lean on the door, lean on the door.

3, looking forward to having a son: passing on the family, passing on incense, the same strain.
