I'm using the very basic one from Babies R' Us brand. I think it's helping me out, but I'm only 5 days PP. The only complaint I have is that it seems a bit too...thin? Like, it doesn't cover enough of me. Which is frustrating, because I know I could wear it tighter around my belly, but my hips and ribs chubs poke out. =/ I only wear it during the day. Either the wrap stretches out a little bit or I can wear it smaller during the later hours... *shrugs* Which one are you using?
The uterus takes 4-6 weeks to shrink all the way down, so I assume the wrap helps until that point. (:
