Am wondering this having read that this is important for differentiating between hfa and as. Ds didn't start saying any words until he was 2. I've checked his nursery eyfs records and he was saying 3 or 4 word sentences by 2.5. He was held back in the baby room due to lack of speech from 18 months to just over 2 because of this. All of his peers moved at 18 months. He is now nearly 6 and has no problems with speech. Quite the opposite in terms of noise and constant chat and singing etc! Would he be counted as having a delay?
