My eldest dd,3yo, has recently developed this speech 'problem', most noticeable when she's tired where she constantly repeats 'erm, erm, erm, erm,' before finally getting her sentence out - it's as tho' her mouth can't keep up with her brain. But the odd thing is that she doesn't do it all the time. (She has a great vocabulary btw and chatters incessantly from morning till night). I and dp find it really annoying and at first started telling her to stop, but this just upsets her and she won't then finish what she was starting to say, so now we've started to ignore it. Anyone else experienced this? Any ideas how we can stop her doing it? Or do we just ignore it?
