DD is 1 and has always been a bit of a squealer but now has begun shrieking in an extremely loud and ear piercingly high-pitched tone. We think its mostly for attention grabbing, but its happening more and more frequently, particularly at meal times or when she is out with me. We tried ignoring it, or distracting her but to no avail so have begun to tell her 'NO' when she does it. Has anyone else got a screamer and if so how long does this phase go on for? Am hoping it will stop when she has a bit more vocabulary.
