I believe this is what you're saying, but to confirm/clarify:

Child: Why doesn't Jimmy have to help me pick up my toys?
Parent: Because Jimmy has to pick up his 'own toys.
Child: But I don't want to pick up my toys!
Parent: Well, Jimmy picks up 'his own toys. Don't you want to be like him?

In general, in English, exceptional stress placed on a word creates a contrast between that word and alternatives for the same syntactic location. While this doesn't apply in the first case, since "his 'own" contrasts with "your," it does in the second, where "his" contrasts with "your."
