How big is a blueberry? About as big as our 7-week child right now! She or he has a heart and even fingers and will grow to the whopping size of a puffed popcorn by next week.
The reality of having a baby is still abstract for me at this point, in case you didn't figure that out from the above comparisons to food. The baby (technically called an "embryo" by the guys in white, but who wants to call their kid that? blueberry is much better) is playing hide and seek inside a belly, and I can only use my imagination to get closer to it. I look at web images of these in-utero beings and with the inter-stellar lighting and dark backgrounds they look like they're floating somewhere in outer space. And right now it feels like s/he is in outerspace. I cannot see it, hear it, smell it, or hold it. Abstract. Yet it's only a few inches away from my fingers, locked inside its own private cabana, lounging in a pool.
Although, while driving with Maren to Santa Barbara recently, some bozo began tailgating us and a protective parental instinct suddenly kicked in; i quickly 'signaled' bozo to back off since i now had a wife with child in the car!
Nothing abstract about that.
