Hi Alix - great post!
I totally agree - just shopped for a bike helmet for Jackson and could not find one without skulls that wasn't too babyish (he didn't want Lightning McQueen or Diego).  Although he kind of likes the skulls (since Halloween - don't get me started) I really don't love the overly mature themes on kids clothes in general.  What's wrong with bugs, or lizards etc?  And don't get me started on the discrepancy between boys and girls clothes -  selection, variety, quantity, holiday clothes.  At least you get to indulge in some of those pretty party dresses now, right?  At least until she's 8 and wants to wear a belly-shirt....
