Tip for Congested Babies

My son is 2 months old and extremely congested so naturally I call the Dr. but there is nothing I can give him. However the Dr. gave me a great tip that I never thought about, roll or fold up a towel and put it under the head side of the baby's mattress. It helps to elevate them and help with the drainage part of the congestion. My son slept so well and I got sleep too :) I can't believe I never thought of this since I prop up myself and 4yr old daughter when we have trouble breathing at night.
