You just gave birth and are wanting to make your child a US citizen.
Here is where you need to look for your forms.
The Consular Section in Florence issues a Consular Report of Birth Abroad (CRBA) to U.S. citizens born in Italy. This is the equivalent of a U.S. birth certificate. Reports of birth are done by appointment only and require the child’s presence.
Report of Birth Abroad – italy.usembassy.gov
“As of February 1, 2008, the two-parent consent requirement for all passport services was extended to include all children under age 16. Either both parents must be present to provide signatures at the time of passport application, or in the event one parent cannot attend, s/he must send a notarized statement of consent and valid identification.”
