I would not recommend the Diaper Genie, however would recommend a diaper pail (it makes life a lot easier than taking out a bag everytime you have a diaper change). We currently use the Diaper Champ and I love, love, love it. The bags that go in the Diaper Genie are so expensive and with everything costing so much today who doesn't want to save a little money. The Diaper Champ, on the other hand, uses regular trash bags, grocery sacks or we use the medium size trash bags from Dollar General. They are the perfect size an only $1 for a role of 48 bags. I think since my daughter was born a year ago I've bought 5 rolls of bags.
Congratulations and good luck!!
