SPD is definitely a thing. Unfortunately it isn't recognized as stand alone disorder, so recognition isn't what it should be. Drs/paed etc won't diagnose it! Without it's inclusion into the DSM-5, it's just seen as a "symptom" of autism etc by many
My daughter struggles massively, and her paed will/can only diagnose "severe sensory difficulties" yet her OT KNOWS she has severe SPD
She wears nothing but plain leggings and plain t shirts (and they have to be boys - because they don't have the stupid ruffles/cap sleeves etc that girl's t shirts have), even at school and probably will always wear that. She also wears them as pajamas for bed.
My daughter also hates showers, as she cannot stand the way the water feels when it hits her skin, so she has baths, and to be honest, even that is hit and miss because the water makes her skin itch!
TBH, it’s a lot more involved than sensitivity to clothes, though that can be one symptom. To be fair, it depends on the severity of the condition, not the amount of symptoms.
Also, let's not confuse sensory sensitivities (can't tolerate tags/seems) with sensory processing disorder. They are not the same. SPD is debilitating.
@Vegematarian I know we're all on the spectrum somewhere NO! We are not. That's is actually a very offensive thing to say, and goes to diminish the struggle that autistic people face. Please do not say that again!!
