One month old won't sleep, is congested, coughing off and on, and spittng up formula. What can we do to help him. We have a humidifier running.

You need to speak to your pediatrician. He/she will tell you what medications to give, if any, and what else you can do.

Until you can get in to the pediatrician you can raise the head of the crib and use saline nose drops.
