S.K.
H.,
My 6 month old has had that since the beginning of August. 4 months and it will not go away. I have taken her to the Pediatrician 3 times. What is going on is that they pick up one cough and before they can really get over it, they pick up another. Hence, it looks like one long cough.
The pediatrician always checks her lungs to make sure they are clear. The last time, because her throat was sore and she was congested, the ped gave me some cough suppresent. Honestly, it doesn't really work that well.
When I move to MN this month, I am going to try again with a new ped to see if she can do anything more. My ped also had us all get flu shots so the baby doesn't catch anything else.
Hope your little one gets to feeling better,
S.
