Sick baby makes me feel helpless.

Erin
My almost 6 month old has had a stuffy nose for a couple months and the past couple days he has had a cough. Poor baby hasnt been drinking much milk because he cant breath. Since he doesnt have a fever they told me there isnt much they can do for him because he is so little. Only bit of information I was given was to keep feeding him the pured foods and pedialyte instead of milk for 24 hours. He seems to be ok, I just feel so helpless that this is all I can really do for him.
