Help me Mommies!

My SO came home a few days ago with a nasty sinus cold. Inevitably it was passed on to babe and I. He's got a little congestion in his nose and has been sneezing a lot. I want to know if you mommies out there know some homeopathic remedies to help make him a little more comfortable. Last night I temped him rectally and he was at 101.6 F. I have saline spray, Vicks vapor rub, and my favorite the Frida Baby snot sucker. Baby is 6months on March 2nd. Thanks ya'll!
