We have used this diaper cream since my little girl was born and have had amazing results. She has only had about 3 diaper rashes in the past 7 months!! We put it on her after almost all diaper changes (sometimes we forget or get lazy) as a layer of protection between her and the diaper. We do use Earth's Best diapers which are chlorine free and I am not sure what role they play in keeping her bottom rash free.We have tried the Desitin Max Strength and found it to be too thick. The tube does last longer because you only need a small amount each time but it is harder to spread and which usually means she doesn't get as much coverage. We also have the Mustela diaper cream that we did use for the few times she got a diaper rash and it was great and making it quickly go away.
