Neither Tolkien (from which, arguably, almost all modern fantasy evolved), nor his pulp-era precursors (Conan, etc.), nor his semi-modern successors (i.e. Moorcock), were aimed at children. The notion of fantasy being aimed at kids is a combination of misinterpretations (sometimes deliberate ones, made by the "high-brow elite" in response to Tolkien), and of authors then proceeding to build upon said misinterpretations.
My understanding is that The Hobbit was made for children, but the later Lord of the Rings was not.
