I'm now 36 1/2 weeks, and I forgot to pre-register at the hospital.
I've done this before...twice. You'd think I'd have the hang of things by now. I know a mother's memory of birth is somewhat wiped after the experience (so that she'll do it again), but somehow I seem to have forgotten everything to do with pregnancy! I've given more than a few blank stares to my OB when he asks a question I should know the answer to. I've blown tests that they assume I know how to do. I actually have been checking up on the Ask Dr. Sears website about the different stages of pregnancy, and how to recognize labour. And I forgot to register at the hospital. I called this morning, but it's too late now (they can't fit me in before I will likely deliver). It's not a big deal - for some reason there's still always paperwork to fill out when you arrive, keeled over in pain and in the midst of contractions. I just can't believe I forgot yet another thing.
I think this solidifies my argument, however, that until you're on your 5th or 6th kid, please do not consider yourself an expert in pregnancy and childbirth. Everyone's experiences are different, and this whole memory loss thing makes it unlikely much of what you say will be relevant to me or that you even recall it correctly.
