My son is 5 months on Tuesday, he’s been having this cough for a few months now. When I took him to his 4 month check up I told his doctor about it and she said he was fine, that he’s just breathing too hard which is making him cough. He still has the cough but I feel it’s now getting worse, his throat sounds raspy when he cries and he even coughs in his sleep and wakes up which didn’t happen before, should I make an appointment with his doctor again or take him to emergency?
