DS aged 2yrs 4 months, says single syllable words - some very clearly (more, no, yeth, cat) some very indistinct (George = goosh, thomas = joosh), won't use two syllables at all even with words that he did previously eg Mummy has deteriorated into (my), nanny = ny. Uses "eee" in place of "oooo" eg says pee when he means poo, bee instead of boo etc.
Social worker wants me to ask for SALT now as she says in her experience this pattern of speech is not normal.
Does someone have experience of how abnormal/delayed this is?
