Query: Great for 6 months- then comes the smell

We registered for this item based on reviews/suggestions. It was great for about 6 months- then it started to smell horrible. I have twin 14 mo olds, and change the bag often. I even contacted the company, they sent me another, and it too smelled after a month or so. Once you put a soiled diaper in it- it reaks!! Also, my kids have figured out how to put toys in it- needs to be somehwhat kid proof.
