Gone are the days of Desitin under your fingernails after every diaper change. The first time a friend gave me the Baby Bum Brush Diaper Cream Applicator, I was like WTF, what is this? It’s literally a spatula for diaper cream! Fast forward a few months and now I even have a travel one. Our night nurse was also like WTF, and now she gives one to all of her new clients so she can use it on any baby she’s working with.
