My heart hurts, just a little

Sometime last week I realized that Mary is weaned.  I'm not sure when it happened.  Though it probably started two months ago when Mary began sleeping like a rock all night long.  It happened without my noticing.  Without a plan, a program, a concerted effort, or even any discomfort.  Which is all something to be grateful for.  And I am.

But I am also sad.  Sad enough to cry.

Mary's not a baby anymore, and I feel as if I didn't get to say good-bye.
