I feel like my 6 1/2 month old has had a constant cold for 3 1/2 months. His chest always rattles.

the ped said it's normal for it to take a while to disappear, especially since he has reflux.

but really? 3 1/2 months?!?! it seems like every time he gets better, he maybe gets another cold or something. But the crackling in his chest has never once disappeared.
