ds1 (5) has dyspraxia and did have speech delay but appeared to catch up. So when he had a salt assessment after we moved the only thing they picked up on was an unusual choice of words and lack of vocabulary. However it seems to be getting worse, and I'm very confused by it. He just seems to forget very common nouns and is unable to articulate clearly. They are things he should know, such as a saucepan (big round shiny thing) and a jumper (yellow cardigan sort of thing). Is this likely to be due to his dyspraxia and what should I be doing about it?
