1. The Convention document doesn't expressly address it, but instructs in several places that the rights enumerated exist for children 'from birth', implying they do not apply to a potential child before it's born.
2. The United States is a signatory, but did not ratify this, and is not subject to it.
I would add that rights don’t flow from documents but rather need to be built up from philosophical argument. Perhaps they’re natural, discovered, or achieved but in any case I think we have to reason towards expansive and philosophically sound rights.
