I too can relate with the clothing issue. My daughter is 11 and was diagnosed when she was 8. We have noticed that when her anxieties are heightened her tolerance to clothing is less. She wears the same type of pants and tops daily and if she can avoid socks and shoes she will ! Her school has a uniform and we have been battling with them for ages to be more understanding when it comes to our daughter wearing the school tie. They have finally agreed to allow her to wear it loosely and not tucked in but it causes our daughter a huge amount of stress daily. Some schools are more tolerant than others, but I find a lack of understanding or lack of knowledge to SPD creates many problems.
