Our son with Noonan’s hadn’t put any weight on for 2 years, although he is growing. The dietician had said to put him on a high calorie diet, basically to give him as much fat as possible. Was this the best thing to do?

Usually the first and most crucial question when a child’s weight isn’t increasing is whether the child is growing. Many young people with Noonan Syndrome are lightly built. There are many issues to consider with diet, as a balanced diet is usually preferred and there is also the issue of the lymphatic function in coping with fatty foods which can be compromised in some people with Noonan’s.
