Hello Doctor, My Son Is 4 Yrs Old And Has

Hello Doctor,

My son is 4 yrs old and has slight temp with cough continuously since morning..the period at which it is occurring is every 2 mns ..his temp has not increased at all and I am giving dolo 250mg once in 8hrs. I have given him Ventorlin last night with Relent syrup too. Please suggest if this is enough to bring down the cough. Is this occurrence normal and will it take a day to subside... when should I see a Pediatrician.

Thanks much,
Shravani
