if you care about your wife returning to pre-preggo dimensions (and you should: her self-esteem, your sexual interest), lobby hard for breast feeding.
the biology of it is that the suckling of the infant stimulates the release of a hormone (can't remember which) that causes the uterus to continue gentle contractions for weeks afterward, helping everything to tighten up again (hips, thighs, belly, hoo-hah).
of our circle of friends with kids, 7 of the 8 women are back in their old jeans. guess which one didn't breast feed?
all of this is not to even mention the vast health benefits to the lil' nipper!
