Is there anyway I can help my newbirn with reflux... i don't know forsure that's what is wrong with him he goes to the doc friday... my first son had it and he seems to have the same symptoms.

He coughs while eating and sounds congested and these are all symptoms of it.. but is there anyway I can help him until friday? I feel so bad for him.
