Regulations on speaking to children have ample precident. We rate movies and age-gate admittance, we don't allow children into liquor stores, strip clubs, or adult bookstores. None of those things violate the First Amendment.
“We” (as in the US government) do not do this. There is not, nor can there be, a law requiring such rating.
> we don't allow children into liquor stores, strip clubs, or adult bookstores
These are physical stores/venues, not written speech. “We” do not restrict authors from writing adult books that may or may not be seen by children, nor do we require that the books are labeled as such.
If you want to restrict speech, pass an amendment. That is the allowable path.
