My son can't smell I think

[Guest guest]

Hi All,

It has suddently dawned on me that my 31/2 yrear old son might not be smelling things.

Is there a way to figure it out? He is non-verbal.

He used to get lot of cold and cough. Had sinus infection.

How do I get this tested? Which specialist should I go to ? ENT?

Any inputs appreciated.

Thanks
