One piece of advice I would give to every person on the planet is this:  Don't touch a baby's hands.  There's this weird thing that happens when people meet a baby for the first time, and I don't know if it's an American thing or if it's universal.  But people have this innate desire to shake the baby's hand like they would greet a fellow adult.  Or sometimes they just want to grab the hand and give it a little squeeze because baby hands are cute. 

Please for the love of Bob don't do this.  Babies put their hands in their mouths.  Like a lot.  And by touching their hands, you're introducing germs, which will inevitably get into their mouths and into their bodies.  Instead, touch their feet, or their elbows, or the top of their heads.  I don't know much about babies, but when I was introduced to one of my friends' newborns several years ago, I didn't know what to do so I palmed its head like a basketball.  This felt stupid at the time, but in hindsight it was one of the smartest things I could've done. #health
