I read this article the other day and kept it in my browser to reference:

During pregnancy, the mother and fetus exchange cells and some of those cells can live on forever in the two bodies after the child is born. 

During pregnancy, cells sneak across the placenta in both directions. The fetus's cells enter his mother, and the mother's cells enter the fetus. A baby's cells are detectable in his mother's bloodstream as early as four weeks after conception, and a mother's cells are detectable in her fetus by week 13. In the first trimester, one out of every fifty thousand cells in her body are from her baby-to-be (this is how some noninvasive prenatal tests check for genetic disorders). In the second and third trimesters, the count is up to one out of every thousand maternal cells. At the end of the pregnancy, up to 6 percent of the DNA in a pregnant woman's blood plasma comes from the fetus. After birth, the mother's fetal cell count plummets, but some stick around for the long haul. Those lingerers create their own lineages. Imagine colonies in the motherland.
Moms usually tolerate the invasion. This is why skin, organ, and bone marrow transplants between mother and child have a much higher success rate than between father and child.

Whoa.

I commented to the husband the other day (before I read this) how I see me in her. How when I look at her, I feel like I am looking at me. I don't think it's because she looks like me when I was younger (because how would I recognise that? I was me, not someone observing me), but there is just this pull that seems more than 'oh yeah, I made her' - she is in front of me, and inside of me.
