I have a 3 year old so the value of my advice might be limited. We had similar issues with clothes. It gets better, but is not worth the battle. My guess based on what we saw here was asynchronous development... So I'd say you probably have a child under 2 who is testing boundaries and your reactions like a 2 or 3 year old. If it is inconsistent, the statements about a shirt hurting are likely more related to her knowing you will take it off if shesays it hurts than SPD... Unless she looks like she is actually in pain. These are really normal phases developmentally, but typically kids go through them a bit older.
