I have never met an autistic person who uses a letterboard or keyboard to communicate saying that they were happier when they were only using a few gestures and glances. Parents who deny their children the right to develop the motor skills for communicating in full, nuanced sentences, paragraphs or even chapters, anger me.
Communication is a human right. The methods exist. If you have the means to get this for your children, do it. If you don’t know where to go, ask me. If you don’t have the money, tell me, so that we can find a way together to get beyond that hurdle.
If you want to come to me with excuses, I will delete your words. You have the right to tell me what you think using gestures and glances.
