I was going to leave this alone, but I need to post a defense of the "unbrushed" haired little girls.
I brush my DDs hair every morning and every night after her bath. Unfortunately she inherited my super fine hair, and she is a rough and tumble little thing.
Every morning, she gets on the bus with beautifully brushed hair, usually in a braid or pony tail, wearing a clean and impeccable outfit. Many of her clothes are hand-made "uniform" jumpers (It is public school uniforms, so I have leeway, as long as her jumpers are the right color).
Every afternoon, Huckleberry Finn-ette gets off of that bus. her hair is a rats nest, and NEVER still up, her clothes are a mess, her tights are stained and/or ripped, etc.
When she is with me, I see how quickly her hair gets in disarray. SHe will rubt he back of her head on the car-seat and get a huge rats nest that looks like I never brush her hair. I was even spoken to by the school social worker about her hair

. Fortunately DD was with me. I brushed DDs hair IN FRONT OF THE social worker, and she went out onto the playground with DH and her brother. Within 15 minutes, her hair was out of its ponytail and looked like I had done NOTHING to it. I got a big fat apology.
Now, my DD is fastidious about what she wears, and prefers my home-made dresses. I know she's rough on clothes, and I deal with it. Some kids are. My DS would wear jeans or jean shorts ad a tee shrt very day of the year if we let him, ad he can't go two minutes without getting something on himself, either. SOme kids just seem to be walking dirt magnets. PLEASE don't judge how involved parents are based on their kids' appearance, either way.
OK, off of my soapbox.
