I'm still awaiting the birth of my first child, due in Sep, but I have experience with little kiddos when I was a pre-school teacher. Once while I was reading a story to the children (they were about 3 yrs old) a character in the story had a beard. I took a moment to make it interactive and asked the kids if any of them had dads with beards. A couple of them piped up, while raising their hands to say "my dad has a beard, my dad has a beard!". One little girl also raised her hand and said "My mom has a beard!"
