I honestly don't know whether YABU or not, because my household is full of "reasonable adjustments" for a child who has autism.
- clothes changing:
The child with ASD went through that precise stage. Is now (some years later) able to articulate the discomfort of certain fabrics, of labels in clothes etc. That child chooses what to wear. If a particular combination of clothes is desired every single day, then I make sure we have multiple copies of each thing (the child wore one, extremely distinctive, combination for six months last year. I kept a few others things around to allow for choice, and now we've moved on to a different preference).
The neurotypical child could not care less what they wear.
- cutlery
The child with ASD is still in that phase. We have enough copies of the preferred kind of cutlery (stainless steel, never silver plate; fork tines must not be too sharp; spoon must not have got worn through and rough edged).
NT child could not care less.
- Room rearrangements
Yes, we went through this phase. It was often to do with getting edges lined up in parallel - child can now talk about how painful it is to their brain when things are not at neat angles.
NT child could not care less.
- Uses all my creams, lotions and potions.
I don't have any creams, lotions and potions ;) I'd have small tester pots for your child's very own, and lock your ones away
- food control
Child with ASD has a pretty varied diet now, but it wasn't varied at 4. Strong tastes, contrasting textures, non-beige colours were extremely stressful to them in food. I fed the child what they preferred to eat, and gradually introduced other food items one by one, with no expectation that they would be eaten (just touching them was an excellent first step).
NT child is slightly less restricted in their food choices than ASD child was at a similar age, but, frankly, having gone through strong food preferences once, I just don't sweat it, and treat them the same way as child with ASD. The diet will become more flexible when they get older
- Receiving presents
OK, this is not in my experience. Both my children are uniformly appreciative when they receive gifts (it helps that a lot of the child with ASD's language acquisition comes from DVDs, where the characters always have perfect manners natch - so the response is always pre-scripted and goes "oh, thank you, it's what I [i] always [/i] wanted; and the NT child just copies that way of responding).
I know this sort of graceless social behaviour from other children with ASD, though - it really helps when their disability is out in the open, so people can give a present to be opened quietly later, or ask explicitly what the child would like, or not take it personally when the child expresses discontent that the gift is not what they actually wanted (like, a real laser gun or something).
- His food can't touch
I know a lot of families where the child has ASD who use those sectioned plates. Or who make sure that the different foods are well spread out on a big plate. We tend to use a series of small plates, and present protein, then veg, then carbs.
Yeah. I'd be looking into diagnosis. I want to say though: I am so grateful to fate/God/the universe/whoever for having sent a child with ASD into my family. We have so much to learn from these glorious humans about what is really important in life, and about how to accept, with love, the quirks of the humans around us.
