One day Addy tried to stick the corner of her blankie up my nose.  Of course I pulled back and was wondering what she was doing.  Then I started thinking about it and wondered if she puts the blankie in her nose.  So I watched her for awhile and sure enough when she sucks her thumb, sometimes she holds her blankie right next to her nose and the corner of it is IN her nose! LOL  It's so fun watching her grow and develop and noticing her little habits.
