The Boy just walked up to me this morning and completely unsolicited declared, "Mommy, I'd be happy to help the Girl pick up all of the toys."
I love it when he tries to talk like a grown-up. I could tell he was pleased with himself because of the way he grinned and capered after I smiled at him and told him thank-you. Now he is eagerly picking up toys with her.
Some days I feel really good about how this parenting thing is going.
