Hi Chris,
I too struggle with the dilema of the activities in life that he may not be able to be a part of throughout his school, and how it may affect how he is looked upon by friends and teachers. What activities did his doctors advise him not participate in? I don't think it absolutely necessary to worry the teachers or schoolmates unless they really need to know.
Besides the deep pectus, his tests for his eyes show no abnormalities, and his heart tests so far show a mild change due to Marfan's but nothing to be worried about thus far. I have noticed he is double jointed in his toes, and may possibly interfere with how he walks----I hope I'm just over exaggerating...I just recently noticed this and have yet to bring it to the attention of his doctor. Either than that he is thriving just as any normal toddler would.
Where is your son being treated? How tall is he??
Our sons are practically the same age, and I would love to keep in touch to compare stories and experiences.
Take care
Daniela
