I'm sorry but everytime I hear any parents or non parents say things like expose them to bacteria cannot be too clean I feel like I'm gonna rage. Though this is 2016 post I'm still gonna rage because they are INFANTS. Every single genius who said that are saying it for their OWN CONVENIENCE. Cause taking precaution for INFANTS is tedious and takes a lot of discipline , time and energy.

Stay away from any parents who said such things and better yet few years later tell you "see my kid ok also" because they are a danger to other kids just like those who refuse to use baby seat, my kid still grow up what. Until they don't.

Waterless UV sterilizer is good because you can put anything that fits into it including toys that cannot be steam, clothe or utensils etc.
