It's full on tween in this house right now, and sometimes I spend a lot of my day wanting to cry.
I know the tween brain's development is responsible for the narcissism, the rudeness, the defiance, the DAWDLING. I know tweens are at the mercy of their developing brains, and that this is a crucial time, I know it, I know it, I know it.
And I know it's my responsibility to get my kids through it. (Hence, the crying.)
