"As I always bite my tongue when I meet little girls, restraining myself from my first impulse, which is to tell them how darn cute/ pretty/ beautiful/ well-dressed/ well-manicured/ well-coiffed they are." --Lisa Bloom in "How to Talk to Little Girls"
I personally disagree. What if your child is gay? Or bisexual? Or into their own gender in any way? You're teaching them to hate themselves. Kids should know right from wrong, but in some cases, this is a bit over the top.
