Someday...

Someday we'll look back and remember when there was just three of us.  Just three people so entwined in one another that a fourth was hard to comprehend.

3 + 1 = 4

That's easy math on paper, but like a million other parents I have a hard time understanding how my heart has the capacity for this much love and affection all over again.  It seems impossible even though I know it's not.

This is the last family photo that adds up to three, and it's such a strange notion.
