Actually I am using dettol in everything but my 3 month olds great-grandmother has whooping cough but she often kiss and play with my baby and didn't listen to anyone his grandfathers take care of cows they also kiss him ..my baby had got pneumonia and blood Infection when he was10 day old and was on antibiotics for 7 days now I can't afford him to be sick again. Earlier I thought he got pneumonia from aspiration... But doc said he aspirate only dropwise that doesn't make difference.. Maybe whooping cough was reason behind pneumonia Now he got cough again from his great-grandmother ..if I give chericoff syrup to my grandma will it stop transmission and vaccination my child 3.5. Month last dose I just want my child to be alive he is on formula from birth I was not having lactation..
