DD is 5 and quite often I have to ask her to repeat herself because she speaks so quietly. Its not in a shy kind of way and she does have her loud times, but it is starting to grate if I am honest. I'm fed up of saying 'Sorry? Could you say that again? I didn't hear you DD'. I'm not sure if I should be ignoring her until she speaks loudly enough for me to hear or just trying harder to listen.
Fancy swapping? Ds1 and 2 are loud and dont shut up. <swallows more paracetamol>
I have always had a quiet voice especially as a child, I didn't have to compete to be heard though as the only child for 5years. I have often refused to shout louder and used to think it hurt to speak louder. So would second the singing suggestion.
Of course you could always throw her into a house of boys and watch her become louder out of necessity as I have found.
I would strongly suggest you get her a digital recorder and encourage her to make a play or story and record it - this will force her to listen back to her voice, strengthen her diction and encourage her to project her voice more so it picks up.
my DD even though her speech is pretty good (I think) for 2.5 no-one at nursery believed she could speak at all until a couple of months ago. My neighbours all (I think) think she's a bit dim because she doesn't say much unless she knows you. But she's not particularly quietly spoken. Is she shy? But if she does it with you then that's not really the issue. Do you think she likes the additional attention that she gets?
