My DS is 3 and spends a significant part of each day reciting TV programmes. He also uses echolalia in his communication, but is getting better at generating his own speech and his functional communication is improving all the time.
His speech therapist (who has now left) said once his functional communication improves then his scripting would reduce, but we're not seeing that. If anything it's increasing. I think it's a stim for him and he finds it calming. He often paces up and down or in circles whilst he's doing it. I also think it gives him something to do as he has very poor independent play skills.
Does anyone have a child who did this and did they grow out of it eventually?
