    ### Response:
    The signs and symptoms of cystic fibrosis (CF) vary from person to person and over time. Sometimes you'll have few symptoms. Other times, your symptoms may become more severe.
                
One of the first signs of CF that parents may notice is that their baby's skin tastes salty when kissed, or the baby doesn't pass stool when first born.
