Well, over Independence Day, one of Dash's aunts (who claims to prefer "Auntie") taught him how to do this with his tongue:
Way to go Auntie. Now he's doing it all the time!
And then my little copycat saw that picture and decided she could do it too...
Dear Auntie: Your niece and nephew are very eager to learn from you. Next time, will you teach them something useful, like how to scratch my back? Love, Meg.

Haha, I love that they both picked that up so well! Adorable! And next time, I promise to try to teach them to scratch your back!

It may be genetic, by the way. Your grandma, the one in Paraguay right now, can't think without sticking her tongue out part way 🙂
