Thanks to Amy Baird for this Frugal Baby Tip!
We use a Diaper Champ and I have no problems with it...not even with smells. I also use nylon mesh laundry bags in them. they are cheap and you can get them at Target or Walmart or any place like that for about $4 a piece. I've never had any issue with dripping pee and poo when taking the bag from the bathroom to the laundry room. But, I also don't soak my diapers (ie in the toilet or with a mini sprayer).
