Noonan's Syndrome: does any one know how to treat this illness?

[Guest guest]

There is a beautiful 1yr/8mo. old girl in my life who has been

diagnosed with Noonan's Syndrom. She does not eat well, is intollerent

of all milk and artificial milk, and experiences constipation. She

weighs less than 10kg, walks, and says simple words. What can here

mother do to get her to gain weight and absorb nutrients? Any

suggestions of mineral rich foods/vitamin rich foods? Thanks
