@DrFell just because it works with girls doesn't mean it's healthy for girls. the girls i know who are not in child care but raised at home are not really that different from the boys. i think it's just might be more easy to make girls "behave" with social pressure.
@bonifartius @DrFell I definitely agree with this, my girls are as wild and energetic as most boys they meet at our local parks. But then again I think they enjoy crafting and other creative tasks just as much.
