I am concerned about S's speech, and nursery are very concerned, and are referring him to Senco over this. One thing that they have picked up on, and I have been sticking my head in the sand over up to now is echolalia - i.e. that S repeats things back that you say to him, and he repeats chunks of telly programmes (sometimes it appears to be at random moments especially when he is tired, otherwise it's a relevant phrase at a relevant time e.g. instead of saying "No", saying "No not a bit (from Hairy Mclairy(!)))
Would be grateful for your opinions.
