My 14 month old had croup in november but still has congestion on his chest. it seems to be making him throw up to clear it and then builds up again?

Croup: Sometimes croup can lead to acute bronchitis. I believe, thechestcongestionneeds to be taken care of. Seek help from your pediatrician.

Talk to your doctor: Croup is usually caused by a particular virus which "stays around" for only a couple of weeks. It can cause thick mucus and that can make a child throw up. If things are getting better, be patient. However, if symptoms are now getting worse or if fever has reappeared, contact your doctor.
