According to Aseky, "If this is not your 1st baby, I HIGHLY recommend adding a diaper pail to your registry. With my first, we purchased the plastic kind, the kind everyone uses and by the time we had our 3rd kid it had a faint odor to it. So we knew it was time to replace it. We decided to go for the Ubbi Diaper Pail. Because it’s made with stainless steel, it will not hold absorb any odors like plastic ones do with time."
