Query: Not a must-have for breastfed babies

We registered for this and believed that it would be an absolute necessity, but I wish we hadn't, at least right away. Because if you breastfeed your baby, the diapers really DON'T stink that much! It's not worth the extra money for the expensive refills, so we've just been plopping diapers in the regular trash can which goes out a few times a week. I have noticed no particular odor since we started doing this. However, once she starts solids, I'm going to get the diaper genie back out and use it again.My other complaint is that the cutting mechanism doesn't work properly. Every time we've tried to empty it, we ended up getting out a pair of scissors.
