Warding Off Germs!

Ally • I'm Mom to 3 beautiful boys. I'm excited to add a 4th little BOY to our family!
What is everyone doing/taking to ward off germs?!  I live in NY, have 3 little boys, and we've been battling colds and viruses since September.  I'm finding it so stressful finding ways to keep myself in the clear!  Any safe and healthy suggestions?!
