I swore by the bikini twist when DD was smaller! It reduces the bulk in between their legs too. Jelly roll also works. If you do a YouTube search for these terms, lots of videos come up that show you how to do them!

I fold them into 4th's intead of 3rd's. Makes for a really thick diaper so you'll need a really good fitting cover to make sure the legs don't gap but it works for us.
Re: Bummis Prefolds HUGE, Help Please
This, or try another fold that would take up more of the prefold - angel wing or bikini twist?
