I agree that it is the tone of posts (including a post completely in bold) which has influence the tone of replies.
Personally as a scientist I find it really annoying when scientifically inaccurate info is presented as fact (greenpeace tried to tell me that the rainforest was essential for penicillin last week buy that's an aside)...
Personally...the definition of natural is without aid.
I would also like to point out that your womb shrinks to its normal size because of hormones...(which is helped by bf)...not wrapping.
Your womb moves to the correct position because it shrinks...deep in your pelvis, there is no way that any clothing/corset/whatever can push it into the correct position because the correct position is so low (and would need to travel downwards not inwards IYSWIM).
And your comments about you wanting your husband to look at you and not sexy mags is shallow. Personally if you are worried about that you also need to worry about your pelvic floor and vaginal anatomy post pregnancy and post birth...cos you presumably want your dh to be having sex with you and not a younger childless model!
(btw you can help retain and regain strong vaginal muscles with excercise...the same is true for your stomach!)
Personally its not for me, as a scientist it looks like either a) tradition for those that live in parts of the world where it is practised and B) a money making scheme for areas of the world where it is not.
(i do see value in the support offered by the belt linked above, but not in regaining the sexy body in the way presented by the op)
