My 4 month old baby is having more cough through me because I have sinus and continues cough problem. What should I do?

Hi I think because you are the mother there is no other way than to keep the baby with you most of the times and it is true also that babies immune system is not fully developed as yet and they can catch infections very easily. I suggest, you take care of yourself and take regular steam and do not let your sinus overpower you. Also you can take doctor's advice as what you can do.
