3) And genetic test found only one copy of gene (carrier) that is F508.
4) another sweat test at the age of 18 months and results ar 44(rhand)/43 (Lhand).

symtoms are
1) poor apetite literelly on Milk 3-4 oz and rice cerial.

Based on the symptoms, I would pursue more extensive genetic testing. There are over 1500 different mutations for CF and mosts tests only include the most common mutations -- so 30-90 out of a much larger number.

DS' sweat test was a normal 32 at about 4 weeks; however, genetic testing showed otherwise. He tends to have more digestive issues. What are your child's stools like? Are they normal or are they frequent, greasy, bulky, very smelly?
