Fun game, right? Do you ever play with a child you don't know well? Bad idea!
I travel a lot for work so I get to meet a lot of babies in my travels. I learned through my own kids that some adults play this game in a very scary way. So, here is my tip:
-Start by smiling at the baby
-Slowly cover your face
-Slowly reveal your face, again smiling
-Do not yell, peak a boo. Instead, smile and softly say hello, or in your silliest soft voice say, "Hello baby..."
Think about this: How would you play with a rautweiler to avoind getting your face torn off? Well, that's how you should play with a baby so they don't get scared.
Oh, by the way, that spinach in your teeth could be scary too. Well, at least it frightens me...lol
