I breastfeed baby and baby is on breastmilk only. I had inflamed sinus, runny nose and sore throat and I passed the virus to my baby. I requested for breastfeeding friendly medicine from my GP. I continued to breastfeed baby and he recovered faster than I do. I think because he get the antibodies from me and protection from the breastmilk. You should be able to get medicine suitable for breastfeeding since its common flu, less serious than mine... Change a GP and request for breastfeeding friendly medicine?
