this is what girls do!!!!!
Sorry, lack of help there.
I am a mum of three girls!!!!and believe me, they do this for ageeeeeessssss.
and sad to say, it lasts until they are about 7.....so for me I have had them go thro this one after 'nother after 'nother, and it gets rather tedious eventually......
soooooo....tips
ignore and treat as tantrum, same as you are doing for you son. they ARE different creatures, believe me, and I can say that as I also have two boys too!!!
tell her you can't hear her until she speaks in a normal voice. will work about half the time, but it does help
if you are in a good enough mood, speak back in same type of voice....the look of shock can be comical enough top stop anything, and also makes me less ranging mummy monster too
my best one tho to work is just to say 'pardon' each and everytime they start.
and then, 'sorry, I don't understand this voice you are using....wheres your nice voice'.
seems to stop it, but then, like I say, I have had three to practise on and so they know how far to take it now.
ooh, and to make it all lots better, it lasts from about 4-7yrs, and then re-starts with puberty....about 11yrs for my DD1, who is now 12 and driving me NUTS[sob]
love them all really
