Thankyou for the input it was very helpful. I have made an appt. with his doctor and can't wait for the results! Thankyou for sharing with me. I don't feel so alone now.
My son had the same thing, I took him to his pediatrician and sent him antibiotics (twice) , which didn't work, I took him to another doctor and gave him a different antibiotic that finally worked, but my son was coughing like for almost two months, so i think you should take your son to his doctor, and if he started daycare not long ago, that is normal they get sick all the time.
