Hello, my two and a half month old baby is sick with cough, phlegm, and a bunch of other things. I'm breastfeeding, and I'm doing injections with ciprofloxacin and lidocaine. Is it dangerous for the child? I can't go to the hospital; there are reasons for that. They will put me in a COVID ward and forbid me from breastfeeding altogether.
