My baby's been phlegmmy, but I know that it's a cold. So I've just been using saline drops, elevating his head in bed at nights, using eucalyptus, etc...
Does your dr just think it's a cold that your baby hasn't managed to get rid of?

I agree with Cheryl, do you have friends with kids who their dr's are? Perhaps they could recommend a dr they find to be really understanding.

Hope you get it all sorted out
