This is possible if antibody testing (ELISA) is the only test you perform.
For a positive HIV diagnosis to be made, blood sample that test positive
for HIV antibodies are subjected to PCR and/or Western blotting to detect
the presence of viral nucleic acids and/or proteins. If these turn out
positive, then you can be pretty darned sure that the baby is indeed
infected (i.e., HIV+).
