Fist bumps, not handshakes: This can’t be more simple! As amazing as kids are, they are all gross. I will say that again! They are ALL gross! There is a lot of advice out there to shake their hands as they walk into your room. That is fine, if you want to get sick 5 times in the first 3 months. Greeting at the door is VITAL and should be done. Just change one simple thing. Give a fist bump, your immune system and family will appreciate it.
