What's with the tongue??

I don't know what it is lately, maybe it's from having a runny nose, but Ryleigh is constantly sticking her tongue out that she is a frog or turtle trying to catch a fly. It is one of the cutest things I have ever seen and had to take a picture of it. Well, when I took a couple more pictures, that's all she wanted to do was stick her tongue out and curl it up. Even when she is laughing the tongue is out. How cute!!
