My son is 4.5 years old. He started out at a very healthy weight at birth of 8 pounds 9 ounces. Since then, he has not even been on a growth chart his growth is so slow. At 4.5 he weighs 30 pounds and hasn't gained weight in a year. He probably has Celiac disease (we haven't bee able to draw blood to verify but he had a very serious reaction to wheat) and I believe his gut is severely damaged (leaky gut) as a result which I am working to repair. He can't eat nuts, eggs, milk, strawberries, shellfish, or even most grains and most allergenic foods.
Right now I don't know how to get him to put on weight. I am sure feeding him lots of sugar would do it, but I want him to be healthy and to heal his gut.
I would appreciate any ideas. TFing doesn't really work for him because he can't eat most of the highly nutritious TF foods. I have ordered him some Dr Ron's liver capsules since he doesn't really like liver but will take those if I open them in his mouth.
I am really worried that his growth will be stunted for life if I can't get him to start gaining and absorbing nutrients properly!
