As far as passing it on to your new baby, I do not know if that is really possible. But you really need to do something, because I know a kid who died of a staph infection. They can be very serious if not treated properly.
I found this for you, if this helps
this is about staph infections
antibiotics—some strains have become extremely resistant to antibiotics—especially in hospitals (1)
resistant to antiseptics, disinfectants(2)
antibiotic resistance:
70% of nosocomial strains are resistant to at least one antibiotic used to treat them (3)
greater than 95% of patients worldwide with staph infections do not respond to first line antibiotics (penicillin or ampicillin) (3)
mrsa—methicillin resistant staphylococcus aureus is wide-spread, if a strain is a mrsa, it is likely to be resistant to many other antibiotics. (2)
more than 30% of s. Aureus infections are classified as mrsa (3)
nosocomial cases can often only be treated with vancomycin (2) because hospital strains are usually resistant to many antibiotics, some are resistant to all but vancomycin. (2)
some vancomycin-resistant strains have been reported in the us, japan, and france. (3)
cases contracted outside of a hospital can usually be treated with penicillinase-resistant ß-lactams (2)
however, mrsa strains, once localized to the hospital environment are making there way out into the community at large. (3)
i think you might need a different atibiotic! I hope this helped you!
