My GS was diagnosed with severe silent reflux at 5 mths. He is now 3 1/2 yrs and has to maintain a wheat, gluten, dairy, egg and soya free diet. My DS is a Coeliac and the paediatric consultant thinks GS is following that route. We know if he has eaten something not right as his tummy distends and he can be sick or have diahorrea, his breath can smell acidic and he makes a weird gargling sound. His behaviour also changes. It was horrid at the beginning but once they had sorted the correct medication and later his diet he was /is like a different child.
