I think we're not meant to be people who give up. We're not meant to lie down and let the darkness swallow us. I think we're meant to rise up, to fight back, to give it everything we've got even when it's harder than it's ever been.
Or, if I'm hanging out with that same mom, we could find companionship in our struggles and lean on one another for support and encouragement to improve our relationship. I could say, "I struggle with that, too. It's not just you." Focusing on the commonality and the fact that we could love each other through the mess would be so much more constructive than writing each other off as a snarky witch who cares only about her super-smart kid.
We want everything good for our kids, and as a parent you discover pretty early on that you'll do almost anything to make your child laugh and to see her happy. The simplest and best way I know to do that is to lift our daughter up to the God who created her and ask Him to protect her, to guide her, to love her, and to help her love Him. Then, and only then, do we feel a little better about sending our baby beyond ourselves.
