My DS is 8 weeks old tomorrow and for the past 2 days he has been coughing - it seems to be getting more frequent and he is coughingin his sleep. He doesn't seem to have trouble breathing except for when he does a little choke (usually after feeding). He has been quite snuffly since birth and I have tried fess a couple of times but that doesn't seem to work. Should I go to docs? I am going tomorrow for his imunisations anyway.
