After E was diagnosed with CF, Dr. R told us that siblings should always get tested as well. We put it off for awhile because 1) they seem pretty healthy to us and 2) we've had our hands full lately just getting used to having 3 kids! I finally found a day that would work where I could take them to the testing center at Children's and my mom could come help me out.
I made sure not to tell my oldest about it too early. She tends to think too much and I knew if I told her about it she would ask too many questions and freak herself out! So that morning when she asked me her usual "Mommy, what are we doing today?" I just said "Well, you know how E has Cystic Fibrosis? We're going to get a test done to see if you have it too. Then we're going to have lunch!"
Sounded like a good plan to her!
The girls did so great. They sat there like big girls and did everything the nurse asked them to do. She used a machine to stimulate their sweat glands and then wrapped a piece of gauze on their arms that they had to keep on for 30 minutes.
Two days later the pediatrician's office called to let us know that everything was fine and their results were normal!
