Why, when girls get together to they have to scream. It does my head in. We went to a party recently where there were several 3 year old girls plus a bouncy castle and the result was high pitched incessant screaming which one parent deemed par for the course whilst another did try and stop it. My ds, also 3, was telling them to stop as he couldnt stand it either. At a farm visit recently there were some 7 year old girls running round screaming insanely whom I had to tell to stop. My ds isnt too keen on nursery as he doesnt particularly like crowds/noise and he refuses to play with any of the girls bar a few because he says they all scream. It seems to me that some parents permit this behaviour as 'it's just what girls do'.
