I used the BelleFit post Partum girdle after my 3rd pregnancy.
In my case, this time around was my 3rd c-section.
I began wearing the girdle about 3 to 4 days after the surgery. I must admit, I was a bit skeptical at first, with the pain and discomfort I had from the c-section I was afraid that wearing it so soon might hurt me.
Thankfully It was actually easy to put on, didnt hurt and when it was on, I actually felt a LOT better. I was able to walk with a straight posture, my abdomen felt more supported and safer.
It was a nice experience. My post-partum swelling was more bearable, I had less trouble getting up & down and around the house and when I held my baby boy I wasn't worried about him hurting my scar area.
I practice the 40 day postpartum home stay, so I wore my corset that whole time and for about 3 more weeks after that in a smaller size.
I know women are all different, but in my case, I believe I benefited from using the BelleFit corset.
I hope this helps!
