Our soon to be 12 year old son has a cleft palate - that was not diagnosed until he was 8 years old!! His lip is fine, but he has a large "hole" in his mouth that is just covered with skin. He also has a bi-fed uvula (I am sure I spelled that wrong!) B/c he was diagnosed so late in life and had already had 4 years of speech therapy, they said it would be devastating to have him go through the palate repair surgery. They said he would need speech for years and would have to learn how to swallow, chew, sing, etc. again. Most people know at birth and the kids can have the surgery way before they learn to talk.
So, he will live with it for life I guess. He cannot smell, does have an extra tooth they are getting ready to take out, gets really bad sinus infections and still doesn't like foods with hard or chewy textures. Other than that, you would not know there was a problem. He used to have really bad bouts of tonsilitus....but seemed to outgrow that about a year or so ago.
Thanks for starting the thread!

We were at POP in February 2007 too!
