Hi. DS (10mnths) has had a cold on and off now for mnths. his snot(TMI0 has been mainly clear, but now it has turned green and he has a nasty cough.. it does not seem to be bothering him,and he is still eating & drinking heaps!! Anyhow, i have bronchitis and on meds, i know this is contagious, and i have been very sick with it. We are off on hols next week, flying interstate.. I am wondering, should i take baby to see dr, can they prescribe him antibiotics? i have been rubbing vicks on his chest, giving him demazin and he has the vapuriser in his room going..
