You can be an absolute woman of women without being a glittery plastic filled Barbie doll. Those are just play toys and not wives and mothers.
There is a lot of middle ground between looking like a Barbie doll and dressing so much like a boy that a girl looks like one.
When I was a 7-year-old, I was what was then referred to as a “tomboy”. My poor mother could not put me in pretty little dresses to play outside because I was climbing trees and frequently ripping my clothes. My most frequent playmate was a boy of the same age 3 doors down the street from us. I just loved being active on the “monkey bars” and building forts. Poor Mom had to just dress me in jeans.
But I never had a boy’s hair cut like this child apparently has, and, when it was time to get dressed for church, my mother put me in girl clothes, and I loved them. When a child is only 7, the parents still have a say in how the hair is cut. Sounds like this girl’s mother has not taught her the side of dressing like a girl, and I suspect mommy likes the attention the ambiguity brings.
You cannot be a woman unless you were a little girl first.
