This comes home to me several times a day right now.
I don't "nest" like most women do at the end of my pregnancy, typically; I do it now, at the end of the second/beginning of the third trimester, and it takes the form of buying lots of baby clothes and an urge to scrub the bathtubs and sinks out frequently.
I don't consider essential many things many parents do for their babies; we registered at Babies R Us and we won't have a crib, won't have an infant seat, won't have baby gates (well I suppose we might put up the one we got for the top of the stairs, and never put up), won't have plug covers, won't have a nursing cover (HATE), won't have a baby bathtub, won't have sooo many things (though I do have a breast pump and will have bottles this time, but not by choice; so that baby can be supplemented with colostrum during her too-jaundiced-to-nurse-effectively period, not formula)... On the other hand, I could NOT live without a ring sling with a newborn! And we did buy a cover for our mattress, since baby will be sleeping on it with us. (Yes, we're co-sleeping-- without a co-sleeper. Again.)
I know many women who have problems with high blood pressure while pregnant. I, on the other hand, have problems with LOW blood pressure.
In all, some of these things are out of my control; some are choices I make. Some I am proud of, some I don't care, some I would change if I could. In the end, I'm glad my family loves me as I am, and I think that the world would be a better place if there was sometimes less expectation of "normality..."
(Ask me sometime about the Naked School of Socialism if you want a laugh, though. ;) )
