I think I have read that curling (into a straw sort of shape) your tongue is genetic....is this true? If dh and I can do it, does this mean that dd should be able to as well....? Or is not as simple as that? Please enlighten me, Iam busy trying to teach (for no other reason except that it is fun to see her try!) 2yr old dd at the moment but am not sure if maybe it is impossible!
