My Kid is 2 years plus and  has some breathing related issues from the past 1 month. Suddenly he starts to breathe fast for 2-4 seconds. Sometimes it happens 3-5 times in 30 mins and sometimes it doesn't occur for even many hours. His X-Ray image shows the deviated trachea but in the X-Ray Report summary everything came normal, his CECT Chest and Laryngoscopy also came normal. We have stopped full cream milk and Pediasure which we have started around the same time when this issue was started. We have started Similac Isomil and for 5 days no issue occurs and during the same 5 days he has chest Congestion and cold and fever for two days also and he was having Asthalin, Monocef, Omnacortil and Alex Junior. Now same breathing issue has been started from yesterday again. We are not getting the proper diagnoses of what issue exactly my son has. It is taking a toll on our mental health. Can someone suggest what to do?
