One problem of my daughter is that she often says "Err Err Err" for a while (3 or 4 seconds) before saying a full sentence.
Probably, she makes that sounds because she can't remember the words right away.
I don't think she stutters because she does not repeat the first sound of some words several times.
Is it correct to say "don't go Err like that before talking" or do we have a more common way of expressing it?
