Ayla'sMama

Hello! I am Nicole, and my daughter Ayla is 19 months old. she sees a ped. GI dr and he did the celiac test but it came back negative. she has many symptoms of Celiac and so i discussed a gluten free diet with her reg ped. and decided to try it. i have NO IDEA what im getting into, all i know is that my daughter is suffering and it is killing me.
her symptoms are- shortness (1% for height), weight loss (from 70% to 25%), easily bruises, constipation, lactose intolerance and a few others that i cant think of right now.

she has been suffering like this since birth (with the constipation) and it has been a long struggle for both of us. i am dedicated to doing the gluten free diet but im really struggling with knowing what exactly i can/cannot give her. i need some good snack ideas as well as some tasty healthy dinners that she will enjoy. she eats lots of fruits and veggies with no problem, but what other things are safe for her???
help! thanks
