Thanks again, everyone! I forgot to mention earlier--in the first 2 or 3 NICU pics, if you look at one of her arms, she appears to have a silver metal circle around her arm (toward the middle/top). That's my brother's wedding ring. To show them how tiny she was (so they could remember it in perspective), they took his wedding ring off and slid it up her arm.
She is definitely a little miracle! She evidently has a lot to do here and was in a hurry to get to it!!
