cough.

my son is 2. he's been having a cough for about 3 weeks now. its kinda a dry, almost barking cough. I was just wondering, should I take him in to be seen? I hate taking him to the doctor all the time. he gets sick a lot, but that's how I was as a kid too. he doesn't have a fever with his cough and he has been waking up a lot at night. I'm not sure from his cough or what, but he used to never wake up at night.

3 weeks, I would have taken them to the dr after a week, 10 days tops. A cough could be more serious than it seems. Better safe than sorry to me.
