Doctors are just passing me to one to another 😭😭

From my pregnancy my wee boy has had his parents. I had a boy born at 37 weeks via normal delivery. He has serve reflux, (possible) cows protein allergy, apnea attacks and had serve diarrhoea for the past 2 months only stops when moved from similac to nutramigen and solids. I just don't know where I stand sometimes jaidens consultant says no milk and then a gp said try him. I have listened to consultant and he had a jar today that didn't say on the back that it contained milk but all of a sudden his face became like this. Has this happened to anyone and has anyone been able to get doctors to listen. Rashes are just so awful looking bless him
