As a child I was terrified of sand. Not just didn't like it, but scared. I hated having it on my hands or feet particularly and even one or two grains in my shoes or socks was unbearable. I was treated as naughty and told off for being slow if I refused to put my socks back on before making sure every grain was gone. Not going to the beach to "pander" to me was absolutely out of the question. I still avoid the beach and DH always dealt with any sandy children when DC were small. I still hate grit in my shoes and don't go anywhere in bare feet or sandals. I wonder if I'd have sensory issues today and if my parents would be expected to be different?
I was also incredibly anxious, especially socially and still am, but the idea that I "couldn't" go to school just wouldn't be tolerated.
I don't think any lasting harm has been done and it's probably true that I cope better socially than I might have because I wasn't allowed to hide from it, but I do wonder sometimes if I'm not NT?
