Post whooping cough for 11 month old

Hi,

I am new to homeopathy and have been trying to find a remedy for my son's coughing and wheezing. Doctors prescribed zyrtec, xopenex, pulmincort and dimethicone to stop rattly chest, possible post nasal drip and wheezing. We did not give him the meds.

He caught a confirmed case of whooping cough 8 weeks ago. The worst stage of cough was June 1-June 15 where he was coughing every hour with stringy mucus. He began to improve without medication though we did use home remedies of garlic and mullein tea. Since then he has had a rattly chest and intermittent wheezing but no more runny nose or mucus that we could see - only hear. The wheezing became very bad in the last few days and doctor again suggested meds. We decided to give him antimonium tartaricum. We have given him the 6C - two pills four times over the last 24 hours. The rattling has disappeared for the first time in two months. BUT the wheezing is still there - gone as he calms down to sleep and returns when he is active. His cough has changed to be more intense and choking sounding but sounds dryer. He wakes (and has since he got sick) every two - three hours through the night- usually with the cough. He sometimes takes up to two hours to fall back asleep. He is usually a happy baby but when unhappy or feeling bad - responds to carrying and rocking. It takes me from 30-40 min of rocking to get him to sleep. He is very active when awake, mouths everything (he is teething and it bothers him alot), and is very social.

My question is - are we doing the right thing with the antimonium tar? When do we stop giving it? I also bought drosera, highlands teething tablets and biochemical phosphates at the direction of a friend (not a licensed homeopath). I have not given him the others yet. I am not sure what our next step should be. Our insurance doesn't cover alternative doctors so we feel very frustrated and hope to get some good info. Thanks!
