'Boy energy' really grinds my gears. I have two girls. I affectionately call her 'spicy'. She is loud, full of energy, aggressive, you name it. She runs rings around the boys I know her age. She is also equally affectionate, kind and caring. She loves princesses, pink and frills, and playing rough and getting dirty.
I would be interested to read more about it being squashed out of girls. To me it is an act of rebellion to encourage my daughter to take up space, to be loud, to love what she loves.
