Hi J., I know how you're feeling. My son has lived with congestion since he was about 3 months old. We use Ocean Spray (saline) constantly and keep a humidifier in his room. When he was a newborn we'd place him in the bathroom with the steam. This really helped. He sees an ear, nose, throat doctor and we were told 'no suction' and to use just saline and then a few drops of baby oil in his ears to help loosen up the wax (it's all relative).
I know this doesn't sound proactive but it really does help.
Good Luck.
