It's taken about five years longer than it should have, but sometime in the last month, G and I finally reached the point where I can tuck her in, give her a kiss, turn out the light and LEAVE THE ROOM. And she doesn't cry! And she doesn't come out every 15 minutes to see what I'm doing! And she doesn't call "Mama, I'm lonely! I need you to lie down with me!" She just says "'Night, I love you," and then I don't hear from her again until morning!
Because mothers are perverse creatures, I'm simultaneously delighted by this and a little sad that she doesn't need me quite as much as she used to. But on balance, "delighted" definitely wins.
