The extra chromosome affects each child differently. They are all unique, individuals. One child can be born with every "text book" medical condition and others can have none. So far, Hailey has had open heart surgery and low muscle tone. We keep an eye on other areas: eyes, thyroid, ears, etc., to be prepared if anything else does come up.
I personally thought my daughter would be a quite, reserved, wall flower. Wow!!!! Was I wrong! She is anything but! She is the loudest, chattiest, most social child I have!
