It's interesting, because I always wonder if putting this type of show on mainstream telly actually (a) interests people who don't have children who aren't neurotypical, who then watch the show and learn something or (b) actually educates people.
It seems to me that people like tiredgirly are watching with their existing perceptions and prejudices and aren't capable of seeing another perspective. I kind of understand that until you have lived something like this, you wouldn't necessarily be aware of things like sensory-seeking behaviour. Or that traditional punishment doesn't work for behaviour management.
@tiredgirly, in case you are in fact interested, in the situation with the milk, the parents may be able to find a more desirable activity which gives Rosie the same sensory feedback as pouring a bottle of milk over her head (this could be a number of things, isn't necessarily pouring anything wet and can seem unrelated, like deep pressure massage or skin brushing). They may be able to replace the unwanted behaviour with one that isn't as disruptive for them. They may also find that her needing that type of sensory feedback is triggered by something, so if they avoid that trigger, her need to feel the sensation doesn't arise. This type of behaviour management for children like Rosie is widely accepted and encouraged by professionals, whereas punishment is pointless and never recommended.
I personally find it quite hard when I am so close to the behaviour to see what the trigger or consequence of the unwanted behaviour is. It's hard not to get bogged down with the firefighting.
