Hi, my DS is coming up to 6 months and has had a chronic cough and congestion for around 11 weeks now. It never goes but does subside. He is a very happy baby and is putting on weight fine. He is exclusively breastfed and has shown little interest in solids. We have tried amoxicillin and 2 reflux meds (gaviscon and ranitidine), all have done nothing. A health visitor has suggested going dairy free. Has anyone had experience with this? The cough does not make him unhappy in day but wakes him at night. He has just stRted sleeping on his front which he is much happier with. He is strong and rolls over back and forth so not concerned. Any advice or experience would be gratefully recieved!
