Ali,
I have not read through everyone's replies yet, but just wanted to let you know how it is with us. At first Tim was very readable, but over time he became more unpredictable. We can never know what his counts are by symptoms. The boy hardly has bruise on his body and he is at 1k most of the time! Sometimes he can have some bruises and be higher. Its not predictable with him. I think its like that with some kids, at least. As time goes on, their bodies change, they adjust to having low platelets. They bruise more easily at times, and less easily at times, and you just don't know what their count is by symptoms. You just have to know if they are low, keep them out of danger. Knowing Tim is unpredictable and can crash one day or week to the next, he is not allowed ever to do contact sports unless he is in a good remission, and even then I am cautious.
