Scrunchie nose

I feel that I need to explain this picture so you all don't think that Madison is a angry baby!!!!
For some reason she makes this face when she is laughing and happy. I don't know who taught her it or how she learned how to do it. She will scrunch up her nose and then breathe in and out real fast!!!
It is the cutest thing but when we are out in public and she does it I find myself explaining to complete strangers that she is infact happy and that is the face she makes when she feels that way!!!
