My toddler called me 'stupid mommy' today, and instead of crumbling, I just felt...tired. Like, 'yep, that's about right' tired. The worst is when they're sick and miserable, and you're up all night with them, and they STILL manage to lash out with some 'I HATE YOU' in between the whimpers. Like, buddy, I'm mainlining children's Tylenol over here for YOU.
