I'm just trying to figure out if I should even be worried about my toddler having CF...he's had some digestive and growth issues so I was here reading and getting some input from the community. My son is very light with beautiful blue eyes...my husband is a red headed man of Irish descent...on the other hand, I am adopted but have been told of Spanish desent..I have very olive skin, brown hair and dark brown eyes...we have another daughter who has my olive complexion and big beautiful black eyes and brown hair..I have 2 other children..one from another marriage (to another Irishman, might I add...I'll never learn! =) ) and one who is adopted. So the two full blooded siblings are polar opposites on the phenotypic scale and the one I'm concerned about is my fair skinned, blue eyed son of an Irishman! Interesting.
