My ds is 31 months and is tiny. He is 87 cms. He falls over quite a bit especially when running. His nursery and 2 docs I have seen say he is fine and normal. But I read an article about ataxia that I just can't get out of my mind. I have been obsessed about it despite both drs saying they think he is fine. I'm always watching him now to see if he falls over. Dh beginning to think I'm going mad and I don't know what to do but I'm getting very down about it. How often is normal for falling over and am I worrying unnecessarily. Some forms of Ataxia are degenerative and there's one called A-T that starts off with mild symptoms and progresses. I keep thinking DS fits some of the criteria in so far that he walked late (17 months) but seems better now but did fall over a lot. I just thought he was a late developer. Am I going mad? I keep feeling anxious because I have read that drs are not that familiar with ataxia. What should I do?
