He seems to be having a problem called spasmodic croup at present which children always outgrow by about the age age of 5 years or so. His parents treated him correctly, running a shower for the humidity is very helpful as is Preflam and nebulising him. He should just as a precaution not eat Zoo biscuits and chocolate although spasmodic croup is not an allergic condition.
I am concerned about the fact that he cannot cry loudly or laugh loudly. He needs to have his vocal cords checked by an ENT specialist to see if they are normal. There is another condition that also causes this problem called a vascular ring or double aortic arch, please ask his paediatrician to check him for this possibility if the ENT says that his vocal cords are normal.
