yeyyow wabbit

[sarahs999]

My friend's five-year-old has a range of speech impediments (if she was to say 'look, a yellow rabbit' it would be 'rook, a yeyyow wabbit'). They don't seem to correct her at all. Should they be? Or is that within the normal range of what's OK at that age?

You don't correct a child with a speech issue. What you do is make sure you model the correct way of speaking. So the response to what you said above is "yes, it's a yellow rabbit".
However you don't do this all the time, plus the SALT may well advise you work on certain sounds, so will only model back with those sounds.

Those sounds, if I remember correctly, are slightly below average, but not worryingly so.
