thanks again everybody for your overwhelming support.
a marginally related note:
There is empirical evidence which suggests that if the mother exercises regularly during pregnancy that the resultant child will sleep through the night more frequently. as well, physically fit mothers seem to have an easier time with labor and have a shorter recovery time.
I've been wanting to get a recumbent exercise bicycle for a while, so maybe it'd be a good investment for everybody at this point in time. perhaps, though, the recumbant position would be unhealthy for the baby, especially once it starts getting big inside my wife... maybe I could get one with a reclining seat. hmmm...
