Your baby started off with a cold which has now infected his chest as well causing an illness called bronchiolitis. The most likely cause is a virus infection called RS virus which is very catchy. The main thing you need to do is to keep his nose clear by using infant saline nose drops twice daily and by sucking out excess mucous from his nose with a mucous extractor.Ask you pharmacist for a nasal mucous extractor for babies.Cough mixtures will not help here.It is important that he can feed normally and can sleep so keep his nose as open as possible. If his cough worsens or if he canot feed properly he must be seen by his paediatrician.
