Are you saying it's irresponsible for soldiers to be good parents? Because there are a few military men and women who might take issue with that.
I'm not sure where you are getting that from and I would rather you not create an issue where there currently isn't one.
1. Most parents couldn't be with them the hole time since they would have to work in order to feed the family, and nothing has a chance against the Dragonborn so the children are under maximum security
2. Moving your family away from places were a Stormcloak/Legion attack could happen to a place were none of the factions will harm them? Seems like a good idea.
3. Skeever plagues are inevitable, and giants won't stand a chance againt the Thu'um.
4. Not only do we have the thu'um, but we have stewards and housecarls to help protect our family, so bandits don't stand a chance either way.
Fair point about the whole stormcloak/imperial thing, for the steward protects them from the bandit raids, I read somewhere that one of the objectives you can get is the rescue family members after they have been kidnapped from bandits so they may not be as safe as you think.
Just to make this clear I DON'T MIND THAT THIS SEEMS IMMORAL I'm not complaining or saying that I don't want to get the dlc or miss out content I just wanted to point it out.
