Just keep telling her that it takes time. I have the same problem with my parents...not a day goes by they don't tellme it looks like crap. "you've got a rats nest back there!""You'll get bugs!""It's not dreadlocks. I'm getting worried, it's been almost two months." I'm just patient, explaining to them it takes time. Every day. Over and over. But your situation isn't exactly like mine, so... Just kiss her and shut her up.
