Most deaf children are blissfully unaware and do not care to think about it. That's until one day they are peer pressured by kin, society or environmental factors that influences them in their choices to get sound.
If he's happy without sound, there's no point in forcing him to use it. You can wait until he's older so he can make a decision if he wants to fix it or not. Until then, try incorporating methods like ASL. If he personally wants to (for different reasons) speech therapy. If he doesn't want speech therapy, don't force him to go.
