I only used this on all my kids bums, it worked like a a charm protecting those sensitive areas. Its a bit pricier than the rest of the bum creams but way worth it.
I love the thick cream consistency that always creates a protective layer around on the outside and soothing from the inside. The pot locks up tight, but its still not "Child-proof" which is something they can look at doing.
And for a even more potent combination for that time your baby's bum did burn mix in it a little bit of Gaviscon ( neutralizes the acridness) and a bit of Mercurochrome (dries it out and speed up heeling)
