My son has been on antibiotics for about 7 days now. I have noticed little improvement in his attitude (he is very whiney) and he still has a bad cough and a snotty nose. The doctor said that he should be feeling better in 24 hours after the first dose. Do you think the antibiotics aren't working?? He shouldn't still have a snotty nose. I take him in tomorrow to see if he needs tubes and he also gets his 15 month shots. I just hope he doesn't already have a resistance to antibiotics.
