ha ha!!! Thank you for sharing everyone! I really appreciate it! I am glad to know that this is 'normal quirk'! She has recently been finding her hair/head, too...and when i put my hand up she'll play with my hand/fingers for a few minutes, and then back to swinging that arm. It's so funny to hear the names for them that you all have used, windmill arm, ax arm, etc. too funny!
