Heloo i don't think a 6 y. old will accept the taste of black pipper !!!

there is many things can cause a cough but a coughing syrup is a big no no , since recently in States they banned many off the market because of the side effects.

if your child got it by being out and got in to cold area just hot shower , good body dry , hair dryer and some vix on the chest will do to cick that cold out.

if not try my chiropractor he is excellent i went there and i saw some informaton in his office about children with cough and breathing problems , he doesn't give any medication which is good for you kid

his name is dr cyrus nassery at american chiropractic center 451 43 43
