Annual Probability of Death in the US

SMHs are 1.6 times more fatal to children than SFHs, 12 times more fatal than firearms, and 44 times more fatal than families.

Of 22.5 million children living in 18.8 SMHs, 422 are fatally abused each year--one death per 44,550 SMHs.
Of 2.1 million children living in 1.8 million SFHs, 25 are fatally abused each year--one death per 72,000 SFHs.
Of 37.6 million children living in 31.3 million families, 16 are fatally abused each year--1 death per 2 million families.
Of 70.1 million children living around 230 million firearms, 430 are killed by firearm accidents each year--1 death per 535,000 firearms.
Of 430 children killed by firearms, 322 are killed in SMHs.
Even if firearm ownership could be reduced by 90%, there would still be 23 million firearms in the US, which would not be much "safer" than 230 million.
Outlawing SMHs would reduce both fatal child abuse and accidental firearm deaths by 70%.
