After reading a few reviews and recommendations, I decided on the Squeem for my post-pregnancy belly binder.  It's even a recommended use on the product packaging.  However I don't think it is the best option for post-pregnancy.  Here's why:

I was already 8 or 9 months pregnant when I started to search for a belly binder.  Most belly binding products tell you how/when to measure yourself for their product for the intention of wearing right after giving birth.  Squeem does not.  I couldn't locate any sizing information.  I didn't want to go off of my pre-pregnancy waist size nor my pregnancy belly size because I would be neither size at the time when I planned to start wearing it.  Squeem had good reviews and a good price so I ended up purchasing this product in 3 different sizes.  Needless to say, none of the sizes fit me at all when the time came to wear it.  Also I noticed on the Squeem that it only comes with two rows of corset hooks and eyes.  This limits the adjustability of the Squeem, so you'll have to buy it in more than one size anyway or hope that your immediate post-partum size is very close to the size that you want to be.

Thankfully the hospital gave me a belly binder and I've had excellent results with it so far.  It is more like the traditional belly binder with the huge velcro strip, providing the adjustability that a post-partum belly needs.  I can adjust the velcro at the top to be tighter than at the bottom if need be.  I've already adjusted it down quite a bit and love the results.  The Squeem seems to be an great product, very well made with quality materials, but I think it is better suited for women who just have a little belly fat to hide.
