All 3 of mine are wankers at the moment, gender irrespective.
Buckled at this 


FabulousChic is there something wrong with some girls wanting to wear makeup and short skirts? 
I don't understand your point at all, sorry. How is it relevant to girls being 'harder work', as the OP suggested?
OP, my 9yo DD is an absolute treasure. Quiet, funny, sensitive, thoughtful, kind - quite happy to curl up in a corner and read for hours on end. Would give you the last of anything she ever had. Would sooner chop off a limb than ever be nasty to anybody. Hates confrontation. My nephews, on the other hand, are a pair of tearaway monsters. Great fun to be around, but fuck me are they hard work. They're determined, stubborn, LOUD, quite aggressive at times, they roughhouse and shout and scream. They're the total opposite of my DD.
None of that is gender related though, they just have very different natures. Plus they've all been raised with different parenting standards/techniques. Whether or not a child is 'easy' depends solely on the child, not their gender. It's a debate for nature vs. nurture, not penis vs. vagina.
So yes, YABU.
